Actual poster from 1917 that made me laugh. A lot.
Also, those motherfuckers are measuring the weight of those balls in kilograms, aren’t they?
Doesn’t the reason why the avg US citizen wants imperial units boil down to “sounds cooler”?
Kilometer vs Miles, the former sounds easier and cooler to work with
Centimeter vs inch, same.
How will they now call a two by four?
It’s kind of the same for the pro gun arguments, it all boils down to “but guns are cool toys!”
Americans choosing the system with tougher math requirements is suprising.
It’s all conservatives clinging to really outdated and stupid shit
We see it as sticking to what we’re used to… As conservative as we are overall, is it really that surprising?
A “five by ten” I would say, doesnt sound to bad.
I think its mostly ingrained into the population at this point.
You forgot that a 2 by four isn’t actually two by four inches .
It is actually 1.5 inches by 3.5 inches. The 2 by 4 references the rough cut lumber before planning.
Planing. Planning wood is very different.
A 2x4 is actually 1.5" x 3.5" so you are not standing on solid ground with that one.
When you build a wood house, how far apart are the studs? I once tried to hang a shelf made by/for the European market, it had predrilled holes that were far enough apart that I could almost hit two studs, but not quite.
How will they now call a two by four?
Stud wood.
Then how to differentiate from 2x6? 2x8?
With a wink. Yes, every time.
Between the kilometer vs miles, isn’t the “former” here the kilometer? So you’re saying the metric system sounds cooler? But then you went on to say two by four which is an imperial thing… am I confused?
Yeap, they got former and latter crossed
Yeah my bad. I meant latter there, and fixed it… Thanks!
They’ll be happy to know the metric system also has miles.
10 km = 1 mile (metric mile)
I have never heard of metric miles, did you make that up?
Also known as the Scandinavian mile. It is very commonly used in Sweden and Norway to describe long distances.
Before the introduction of the metric system, there were many local miles. Some a bit shorter than 10km, some a bit longer.
Ah, perhaps not as standard as I thought!
Ugh, who wants to change to a base-10 system when we keep what ever we have now?
I mean there’s really only four ways people use imperial over metric
For cooking, For weighing themselves, For measuring distances, For measuring temperature.
For most other purposes, especially where scientific accuracy is called for, Americans are perfectly aware of and capable of using metric, and mostly do so.
Metric pushing at this point is basically bashing non academics for continuing to use a colloquial measurement that serves them just fine for what they actually need to measure and visualize on a daily basis.
Cooking has largely moved to metric (with the exception of spices/seasonings, weighing spices is tedious compared to spoons IMO)
That depends more on the setting, IDK about professional kitchens but most home cooking I’ve seen measures in imperial.
I’ve seen them chiefly in US Customary.
A decent chunk of recipes I use are for baking (where weighing is important and grams are standard) so YMMV, though I don’t generally eat a lot of “american” food so my perspective is a bit skewed toward metric.
Tbf a decent amount of “american food” is prepared by intuition rather than by formula
If you’re checking measurements for a burger, it’s for the individual stacked items you’re putting together on the burger and not usually for how much ground meat you need to get off a chuck steak for the burger you want.
I only write down measurements in my own recipes because I’m chronically paranoid I’ll fuck everything up since so much of my stuff is already mishmash of previous recipes (just finished putting together a non dairy Knaffeh recipe so my SO can have it in spite of their allergies, had to figure out how to mimic Arrakawi cheese using fake mozz lol XD)
I have never seen a US cookbook or Internet recipe site that defaults to metric.
I clicked the King Arthur link and the recipes default to English with metric in parenthesis.
You forgot one: Fasteners, i.e. nuts and bolts, when all the rest of the world has been metric for decades and whatever it is you’re taking apart almost certainly uses metric bolts (car, appliance, electronic device, whatever). But your local hardware store still gives you attitude over metric being ‘’‘’‘’‘‘specialty’’‘’‘’‘’ and the majority of their selection of bolts and machine screws are fractional inch which will not fit approximately 9.98% of all manufactured goods from the last century, let alone this one.
At least be consistent with it too! I don’t know what it’s like in the States but internationally we don’t get 7/16" bolts or whatever, we get 10-gauge or 8-gauge etc. What the fuck does that mean?? And wiring too: no 8mm wire, no no let’s have 6AWG. Jesus christ it’s like they enjoy making life difficult.
Having two sets of wrenches and sockets is absolute worst. Especially when it seems like 10mm does 80% of the work but is missing 100% of the time
Those 10mm are pros at hide-and-seek.
I found a 10 pack of 10mm once. Bought it immediately thinking I’d never need another 10.
That was 5 years ago. I have 2 left…
Imperial is intermixed woth metric in constructionnand a ton of engineering projects as materials are still manufactured in imperial measurements. Farming is still stuck in imperial too.
Both are still around because an entire industry changing fundamental measurements is a lot of effort.
My second favorite example of the two living in harmony for the average US citizen is the liquir store. Beer comes in ounces but hard liquir and wine comes in metric.
My favorite is soda, which comes in 20 oz and 2 liter bottles on the same shelf. People opposed to the metric system tend to ignore the fact that they are already using it somewhere in their lives and just don’t notice.
My favorite weird imperial/metric oddity in the US is 16.9 ounce bottles. People refer to them as “sixteen point 9 ounce” bottles. They’re 500ml. It’d be so much easier just to say “500 em ell”
Mine is that the most rabidly anti metric folks stateside are likely to be weapons enthusiasts who measure ammo calibur in metric.
Nope, beer is measured in Fluid Ounces which is a measure of volume and is entirely unrelated to ounces except for having the same name. Oh also a fluid ounce is a different amount of volume depending on the context. It’s a greeeeaaaaat system.
That is an interesting clarification, not a correction, because nobody calls them “12 fluid ounce cans.”
Well, yeah. We are trying to make things easier for You.
Oh yeah, because constantly forcing a change it’s obvious nobody you’re trying to force it on cares about is definitely making things easier for them.
The metric system is a threat to our way of life - Kyle
1917 shitpost with obstinate opinions held to this day. Brilliant!
I don’t think anyone believes the current system to be better, rather too much of a pain to replace. Americans really dislike learning and being inconvenienced.
Hundreds of millions of people learned the new units when their countries switched.
Australia joined the metric system on the 14th February 1966. It took about two weeks before it was running trouble free. Everything changed, including currency, on a single day. The system is pretty easy.
True! We used to use pounds, shillings, pence as our currency and I’m very glad I never needed to deal with that shit.
Inconvenienced might be right. The tagline from the poster treats metric implementation as a punishment. “What has he done to deserve this?” Has the same victimized tone like, “Look what they done to my boy” which completely disregards the merits of either system in favor of nationalism. It almost seems like a cold-war era ideal.
Start with adding a few metric characteristics in imperial. A yard and a meter are pretty close, so call it a kilo yard and centi yard. Same for quart and liter. It’s not switching to metric, but it’s more logical.
Americans really dislike learning and being inconvenienced.
it’s worse than that-- we have gallons of milk, but liters of soda. we drive in mph, but run in 5K. science and medicine weights are grams, but recipes call for ounces. want to fix an american car–hope you have both metric and “standard” wrenches
more like we’d rather stay with the stupidness and inconvenience we know rather than change anything, no matter how much better it would be
We are used to 2 liter bottles, so we still use them. We run 5ks because its been a standard distance to run for a long time. Other countries also do similar things, old habits die hard.
We use metric for science and medicine because the benefits of metric are much more pronounced for those use cases.
Honestly, using both really isnt that hard. Its only really an inconvenience if you aren’t already used to it. We aren’t changing it because we’re getting along just fine the way things are, and there are much bigger problems to be solved.
for one thing, there will always be “bigger problems to solve,” just like with getting rid of DST, which also needs to fucking die a horrible death already
for another thing, thank you for providing a perfect example of my last sentence
American are willing to change things, we just pick what to change, and we aren’t being inconvenienced by this nearly enough to change it.
thank you, again, for illustrating my point. again. care to say the same thing a third time? for the people who just aren’t getting it?
By continuing to act like this you are preventing any actual conversation from taking place. You might as well just say “you’re wrong, no I will not elaborate”. If you’re not interested in having a conversation then don’t respond, no one is forcing you to do this.
If you would like to have a less sarcastic and rude discussion, I’ll be here.
want to fix an american car–hope you have both metric and “standard” wrenches
I will point out that with the singular and shining exception of lugnuts, at least this one has not been the case since at least the 1970’s. All fasteners on current(ish) American cars are metric nowadays and have been for quite some time. I’ve never seen a single one that isn’t on any car that’s not old enough to qualify for historic plates.
This used to piss off the oldheads to no end back when I managed a hardware store because they would absolutely insist, sometimes literally screaming in my face about it, that their dang old good old boy red blooded American Ford that they just bought didn’t have no Jap pinko metric bolts in it anywhere not nohow, and 100% of the time they were wrong. (This annoyed me only slightly less than the people who showed up needing a bolt, didn’t know what it was, didn’t bring the old one with them, and the only information they had was “I took it off with a 9/16 wrench.” Hombre, the head size tells me absolutely nothing about the diameter, thread pitch, or length. Then they would claim that it’s just a “standard” bolt, as if there’s any such thing. Also, a 9/16" wrench will usually fairly easily remove a bolt with a 14mm head, so that really tells me nothing. Or 5/8" on 16mm. Etc.)
Harleys, however, take it as some kind of point of pride that they actually do use fractional inch fasteners everywhere.
The differential bolts on my ford 8.8" are 1/2". Also the lower intake manifold bolts on a gm 3.8l were 3/8" even though everything else was metric. I’m sure there’s also oil drain plugs that are not metric.
didn’t know what it was, didn’t bring the old one with them, and the only information they had was
LOL the library equivalent is “i’m looking for a book but don’t remember the title or author, but it was about a woman who fell in love, and it had a red cover!” which describes a not-insignificant percentage of all books in existence
That, and different editions and prints of different books can and will have different covers.
Might even have different names:
See also: the 9mm and 5 grams in my pockets
LOL i’m sure the multiple units of measurement for ammo is worldwide-- thanks USA! but yea, drugs are always metric
Except for an O
Dealers always know the approximate grams to ounces conversion, which coincidentally works out in their favor an extra ~1%.
Except that it has been replaced, or is not the preferred unit for trade and commerce. The SI has been the “preferred system of weights and measures for United States trade and commerce” since 1975 according to United States law. Too bad most other Americans are too scared of change to use it everywhere else.
All I can say is that the metric system was predominantly taught in my American school experience, with US units mainly limited to math class. The only thing that sucked about using metric in science class is the short unit we had where we needed to convert measurements between metric and US, which I think was arguably the point.
It’s corporations, really, that seem to insist on having their products and tools still defaulting to US customary units, and I can’t fathom why. Even when you go abroad and try to buy a TV, they’re all still labeled in inches, which boggles my mind.
It’s corporations, really, that seem to insist on having their products and tools still defaulting to US customary units…
I am no corporate fan, but this one is not on them. They already sell the same products in metric everywhere else. If the US switched to metric, most corporations would be able to switch overnight.
Not likey, the production lines used to service other countries are probably not the same used to supply the US.
New equipment would have to be obtained, new processes developed based on differences with regional suppliers, different regulatory standards on the production process would have to be adhered to, and they’d lose out on the generations of compatibility with older standards that they are intent keeping as cost saving measures.
Overnight is a stretch, but could they switch given enough time? Almost certainly. But it’s a major unnecessary expense that doesn’t immediately benefit shareholders.
Did you go to school in the 70s or 80s? I don’t think it’s like that anymore.
Probably depends on state. I went to high school in Washington state, just about a decade ago, and we were taught SI units in most science classes. Unit conversion was almost always one of the first lessons we had. Chemistry specifically made us learn sig figs, which is much easier to use with SI units, and made me wish we used them everywhere.
That’s probably what it is. I didn’t go to school in the US but my kids went to school in Ohio and my impression was that metric was not the primary system of units used in education, though it was taught.
The argument I hear most often from people defending the US customary units is that the units are more intuitive. For example, an inch is about the size of a thumb, or 0 degrees is fucking cold and 100 is fucking hot.
On the whole, people seem receptive to metric, but don’t want the hassle or cost to convert. They seem content to use metric where it’s important (science, military) and keep the old ways elsewhere.
I currently with in healthcare research and almost everything not patient facing is done in metric, but there are still conversions going on everywhere, leading to data problems that are hard to correct later. People used to thinking in ounces putting those where grams were supposed to go, and so on.
I doubt the corporations care in any deep way, same as with anything else. It’s just sort of a chicken and egg thing. They’ll resist change as long as resisting is cost-effective, but that very resistance slows adoption. Still, they will likely shrug and adapt if it becomes obvious that people prefer metric, or even simply stop caring.
I don’t think anyone believes the current system to be better,
Check our ShitAmericansSay (on Reddit, ew) and you’ll find plenty who argue that metric is worse.
Metric is undoubtedly an improvement, and if there were political will, I’d be all for a renewed push to make it the sole standard. Cultural inertia within a single large and wealthy country is pretty much the only “advantage” the older “system” has over metric.
I do get a little bit protective when people suggest that Imperial/Customary/whatever is nonsensical or useless, though. It’s more that it’s disjoint and obsolete. Units arise out of circumstances, and shit like using 12 inches to a foot makes a lot of division into fractions really easy. Same with 8 ounces to a cup, 16 to a pint, and so on. Dividing shit in half or thirds is a pretty easy paradigm to do math in your head if you’re not really getting a lot of formal education. Most of the base units ultimately trace back to something perfectly sensible for a pre-industrial society.
So there’s method to the madness, it’s just that it was a thousand different methods, arising from various trades and merchants trying to standardize (yet also retain) their traditional measurements for their own needs. There’s not the grand unified system that only really became workable with standardized manufacturing and improved communication in the 19th century.
The other funny thing is that while units can and do still cause confusion, many US Customary units are literally defined in terms of SI and have been for well over a hundred years. An inch, for example, is exactly 2.54 cm, because even in the 1890s Americans knew it was stupid to try match a metal stick in London to one in Washington to one in Paris with any greater precision than that, and only the SI had a set process to refine unit definitions in relationship to natural phenomena.
Although, to be fair, British people say that too, especially when Britain joined the EU. “You mean I have to stop measuring the produce I sell in pounds and ounces?!”
And, of course, they still use MPH. I imagine there would be a massive uproar if that got changed.
British have gone much further with metrification than the U.S. but there’s still way too much resistance. And some of it is very silly indeed- weighing yourself in stone, which is a rather arbitrary 14 pounds.
7 pounds = 1 stone… got it. How much rock = 1 stone then? Or is rock more than stone?
Both have to be more than a pebble, right?
I did say that we hate learning. 😉
It has nothing to do with disliking learning. Trying to learn and use a system of measurement without being immersed in it is really hard. For years, I’ve set all my temperature measurements on my phone and thermometers to Celsius, but because I’m surrounded by people and systems that don’t use metric, I have to convert back and forth between the two. It’s a lot of mental effort for basically no gain.
Every day, customary speed and distance units and my intuitive understanding of them are reinforced when driving and seeing street signs. I know how long a kilometer is, but if you say “My brother lives 45 kilometers away”, I’d have a difficult time truly understanding that. I wouldn’t be able to estimate how long it would take to drive there, for example.
Another issue is cost. In my job, it would take weeks or months to update all of the documentation and code to metric. Then customers would have to approve of all those changes. A whole bunch of machinery still uses customary units too, so they would have to be replaced or updated.
I say all of this as a metric lover and evangelist. It’s not trivial to convert an entire massive country to metric. Countries that have converted already should be hugely proud of themselves for accomplishing a difficult task.
Doesn’t need to be instant.
You can have a year or two where both metrics are given side to side on products, weather,…
Even road signs can just slowly update by hanging the new signs next to the old ones for a while, until the old ones are removed.
It is about disliking learning and the need to be contrary to the rest of the world.
There’s always the option to be stuck in an infinite transition period, like in Canada. I was appaled the other day when a buddy of mine used °C for air temperature, but used freedom units for water temperature. The same applies to heights vs distance and speed, weights… It’s all kinds of cursed.
I think younger people in Canada only know °F if their thermostat is set to it and they can’t or don’t bother to change. My stupid fridge is in Fahrenheit and that can’t be changed (even though the handbook shows the display in Celsius! A variation of the model is probably sold abroad).
I think Canada properly adopted Celsius, kilometres, litres and millilitres (at least here in Toronto), but all other metric units are the underdog. Even CBC, that is probably the only media outlet that tries to stick to metric will specify people’s height in feet and inches. Shameful.
Canadian here. It really depends on if it’s a cultural use or something the government might have an influence on through legislation. They can force industries to label packages in metric, but they can’t force grandma to change her manually-transcribed recipes. The other big influence is obviously our neighbours to the south. A lot of industries haven’t switched over there, and we get their products. Main culprit here would be the construction industry, lumber and hardware is all in US customary units and I hate it.
uncle sam you dense motherfucker go to SCHOOL
How many centimeters in a kilometer?
How many inches in a mile?
Strange how you can easily work out the former, but the latter could be anything from 28 to 56285794
🤔
Km is 103m cm is 10-2m so the difference is 105 i.e. 100000 (one with 5 zeroes)
Or more intuitively one centi-meter is a 1/100 of a meter and Kilo-Meter is 1000 meter therefore 100*1000 100000
It is quite intuitive, once you start using it
What’s weird is why we don’t use Megameters and megagrams (i.e. one metric ton)
How many liters is 1 square meter of 1mm thick steel?
I’m definitely on board for megameters. One AU is about 150 gigameters and 1 light year is about 9.5 terameter!
1*10^-3 m^3 = 1 dm^3(AKA liter)
American answer: “Shut up, Euro-freak. I’m trying to watch Big Bang Theory reruns.”
My comparison is that the metric system is like color vision. It’s like colors for traffic lights, but USC people insist it’s fine memorizing which light is which location. In metric you just see the world in a way USC can’t, but USC people insist they’re just fine.
The medical system ended up using the metric system anyway
America has medical system?
It’s more a system of an abuse and profit than speficially “medical”. That anyone gets better is purely a marketing/sales feature.
Nope, that’s why they didn’t duck up with it
This is his punishment for war crimes.
It’s possible! We can switch! I’m US born and raised and I voluntarily switched to metric in college. It took me maybe we few months to start building an intuition for Celsius, grams, liters, and meters. And that was with me in isolation. I would imagine it would be much faster if everyone else was also transitioning.
Over the years, other people have asked me about this and I’ve been shocked at how many people don’t realize most of the world uses metric. Someone asked why I was using “Mexico units” once… Also, I’ve met lots of people who think the US invented inches, pounds, etc, which is… uh… interesting. The arguments y’all are having here are way more advanced than what I’ve run into.
For anyone who wants to voluntarily switch, I highly recommend not to convert between imperial and metric. Just read the metric number and that’s it. The weather says it’s 25c outside? Don’t convert to F. Go outside, experience 25c. Over time you’ll build an intuition. Smartphones and computers have made the switch easier these days.
Of course, until we all switch you’ll really end up being bilingual…
It’s also helpful to remember that water boils at 100C and your body temp is about 36-37C. Helps me when I see the weather or something.
Room temp is ~21 degrees. That helped me a lot.
I wish
Of course, until we all switch you’ll really end up being bilingual…
Biunitated?
For me it was particularly easy as it’s only Chevy and Ford cars that still use the imperial system for nuts and bolts so I’ve been making use of the metric system for pretty much every car I’ve worked on and I never really understood ferinhight to start off with as I only really cared about is it going to snow temperature wise so why memorize a number for something your only going to check one time in the year now that I’ve gotten accustomed to Celsius I’m now paying attention to if it’s going to rain or not
We actually were transitioning to metric when Carter was president and making progress. We did a lot of dual markings like highway signs, weather reports, etc.
The we ejected Reagan. And metric is used for pop and drugs.
Drug dealers just know what units system is superior
I stopped caring about British units in 1776! Metric all the way, baby! 🇺🇸 We decimalized their dumb ass currency and we need to finish the job with weights and measures! A vote for imperial units is a vote for red coats! Vote for me for President and I will liberate us from British tyranny! 🇺🇸🇺🇸🇺🇸🇺🇸 🦅🦅🦅
Lab rat here. I got you fam! Let’s collectively believe that BTU’s are real!
Wait…
The idea that a simpler system of weights and measures that operate in base-10 will somehow cripple America is somehow fucking hilarious.
From John Bazell “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.”
But we’re supposed to use Joules, not calories
I believe the calorie is a derived unit while the Joule is a base unit.
Somebody correct me if I’m wrong.
The calorie used to be the base unit, until we released in the 19th century “wait, heat isn’t a gas” and threw out caloric theory, and made the joule. Now the calorie is defined as 4.184 joules.
Yes, you’re right.
There have been multiple iterations of the “metric system” since it’s introduction in 1792–1795, most notably the original 1795 draft variant, then the CGS (Centimeter-Gram-Second) version, then the MKS (meter-kilogram-second) variant, with the most recent incarnation being the International System of Units (SI).
That’s why there are plenty of metric units, but not all of them are SI units. :)
Edit: Changed “1892–1895” to “1792–1795”. Lol, whoops.
It’s demonstrative anyway
Applied to a real situation I’ve been through :
- my pool 4.5m wide, 9m long and 1.5m deep, the current level of salt is 2.5g/l and a bag of salt weight 20kg. How many bags of salt do I need to bring the level to 3g/l ?
- OR: my pool 14’9" wide, 29’6" long and 5’ deep, the current level of salt is 2500ppm and a bag of salt weights 40lbs. How many bags of salt do I need to bring the level to 3000ppm ?
The answer to one is 1.5 bag, the answer to the other one is “fuck that, I’m getting 8 bags at the store and it should be good enough”
Or they answer in BTUs. But ask them which BTU they’re using, and they won’t know.
Calorie? Are they part of metric system? Everyone uses Joule.
Calories are metric but not SI.
There’s a popular argument against religion that essentially says that if any trace of a specific religion were wiped off the face of the Earth, it would never come back. As in there’d probably be something in its place, but there’d no way that the specific beliefs practiced by that religion would ever return. Whereas if a piece of scientific knowledge were similarly wiped from human knowledge, it would eventually be rediscovered.
A similar argument can be made with the metric system: I think that if standardized measurement systems disappeared from the face of the Earth today, something extremely similar would eventually be invented and adopted. It’s just too internally consistent and human mental math too grounded in decimal for it not to be. You’d probably even end up with a prefix-based (probably even Greek) naming scheme.
Now consider USC: the units fail to fit together in basically any meaningful way. They try but fail to be base-2, so you can’t even come at it from the already-tenuous angle of base-2 being better than base-10 (e.g. volume skips what two quarts would be, weight is more like base-16 (???), and distance just does something so insane that probably 95% of American adults couldn’t tell you how many feet there are in a mile). There are dozens of completely arbitrary, unintuitive, antiquated-sounding names (e.g. “horsepower”). Although the bases for metric measurements are rather arbitrary, they are extraordinarily precise, so much so that USC bases its own measurements off of insane but precise multiples of metric units. That’s not to say that humans would jump straight to metric or anything, but moreso that whatever would fill USC’s role as an intermediary between nothing and the metric-like system would likey be unrecognizable from current USC.
I would agree with you that something similar to metric would eventually arise, but I would consider duodecimal to make more sense than decimal, as 12 is a superior highly composite number and the terminating representation is much shorter for more commonly used fractions (e.g. 1⁄4 would be represented as 0.3, 1⁄3 as 0.4, 1⁄2 as 0.6, etc). I would also argue that groupings in powers of 12² make more sense than 10³.
I would also argue that it would make more sense for measurements to be based on natural units (such as Planck length) for all the basic measurements (second, metre, kilogram, ampere, kelvin, mole, and candela), such that the anthropic unit (the one you’d most commonly refer to without prefixes) would be some multiple of 12 away from the natural unit.
The “intuitiveness” of imperial measurements is that they’re sorta human-scaled, at least for human-sized measurements. An inch is about the same length as the tip of my thumb, a foot is about as big as my foot, a yard is a single pace if I stretch a bit, etc. which makes it easier for a person to picture it.
Once you get out of that scale it really starts to break down though.
Yeah, the thing is that I actually don’t terribly mind feet, cups, etc. as individual measurements. Taken alone, they feel intuitive. The first of two main issues is, as you mentioned, scale. And you could make the argument that you could just take the base units like feet, cups, etc. and decimalize them with prefixes. And that does alleviate a ton of problems with USC, but you also then run back into the issue of unit intercompatibility.
Metric units have quite an elegant and intuitive interplay that USC simply lacks. What’s a liter? Why it’s a cubic meter. But now if I try to relate USC volumes to cubic USC distance measures, things quickly fall apart. A gallon is 231 cubic inches exactly, which is a whole number, sure, but that’s terrible for intution and for scaling. What’s a kilogram? Why it’s the mass of a liter of water. If you try relating pounds to units of volume, you might settle on one pound per pint, but that isn’t true, as it’s actually 1.041 pounds. So while it works at that scale, it quickly begins to fall apart and becomes completely inintuitive.
So unfortunately, even if we introduced intra-unit scaling by choosing one base unit and scaling that, working with USC would still be a nightmare when trying to intuit between different units. And this is, of course, not including things like horsepower that may have been intuitive 150 years ago but now are almost exclusively used 1) at minimum in the hundreds and 2) by people who have literally no concept of how much a horse can turn a mill wheel.
I mean, 1btu is required per pound of water per degree Farenheit. About 8lbs/gal and raising it 142°f would mean 1136btus
Removed by mod
So intuitive!
Just remember to keep track of which BTU you’re using
Lol also which gallon for that matter
centigrade
and he was doing so well until this abomination 😡
… weighs one gram … An amount of hydrogen weighing the same amount has exactly one mole of atoms in it.
Not only was this never true - the sentence would have to have say “An amount of carbon-12 atoms weighing 12 times this amount has exactly 1 mole atoms in it” (far less elegant) – but not even this is true any longer after the fuckup in redefining the mole in 2019, after which all these relations between amount of substance and mass are only approximate.
the fuckup in redefining the mole in 2019
What? It was necessary due to our observations of the universe (on every scale), not some subjective “fuckup”
Nope, this redefinition isn’t necessary, it is a choice SI made. Nothing would have broken by keeping an exact relationship between amount of substance and mass, it would just have retained the interpretation of Avogadro’s constant from before 2019 (experimentally determined vs a defined constant).
