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?
As an American who lives and travels on a sailboat, it’s sooooo much easier to just be normal and think in metric.
Foreigners (who aren’t sailors) are always amazed when they meet an American that can speak metric.
Why the US refuses to get in bed with the rest of the world is beyond me. Stupid AF I guess …
1l of (4°C) water weighs 1kg. 1kg (of anything) is 1000g. 1g of water is 1cm³. Stack 1000 1cm³ blocks to get a 10m high column. This column exerts 100kPa of pressure on its base. To heat it by 1°C requires 1kcal. And 1N would accelerate it by 1m/s every second.
I’ve posted this before on my mastodon, and on feddit.de, before the instance was shut down, but I think it’s still a nice showcase how SI units interact with one another.
The worst thing we have in the metric system is kWh/1000h. It’s just watts, but whoever designed the energy labels thought a bunch of zeros would be funny or something.
The kWh/1000h does convey more information than just W though. If I buy a fridge and it says 100W I wouldn’t know if that’s its max power draw or average over time. With the 1000h in there it’s pretty clear we are talking about the average.
Also people who aren’t technically minded might only know “kWh” as that’s what it states on your power bill and they can directly guess what kind of energy bill this fridge might cause.
So you are technically correct I guess and we all know that’s the best kind of correct.
We do have worse stuff in the metric system though, kcal is not the same as the SI for energy (J) for example. Also everything involving time gets messy quickly. Nothing compared to the imperial measurements obviouslyI’ve heard that kWh/1000h is used as a power rating for light bulbs, because if they just wrote it as watts, people might confuse it with a brightness rating (e.g. “this LED bulb produces as much light as a 100W incandescent bulb”)
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.
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 be 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.
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.
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”
I mean, 1btu is required per pound of water per degree Farenheit. About 8lbs/gal and raising it 142°f would mean 1136btus
that’s a lot of words and numbers for, “go fuck yourself”
Just remember to keep track of which BTU you’re using
Lol also which gallon for that matter
Or they answer in BTUs. But ask them which BTU they’re using, and they won’t know.
… 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 arbitrary “fuckup”
Try farming in Canada. I will actually use liters per acre as a unit to measure in liquid fertilizer into a sprayer, spray it at gallons per acre and drive the sprayer at kph with a pump pressure in PSI on a field that was surveyed in rods.
It’ll get harvested by a machine that has all metric bolts and uses a 30’ cutting platform, the grain will be measured in bushels on the yield monitor and sold in $/bushel with the selling agent but the contract will be in tonnes and delivered that way.
And you have to do it in two languages too.
Well, chances are the Quebecers will have to learn English because I think ag equipment is exempt from dual language laws. At least I’ve never seen a part number for French manuals.
The US Government is entirely metric. It’s just the US Citizens that aren’t. So there’s this entire separation where no one uses metric, so nothing is made for metric, since nothing is made for metric, no one uses metric.
Obviously that’s changing over time plenty of people use a mixture of both systems all the time. The machines are mostly driving adoption at this point. 3D printers, cars, etc.
Jesus this is dumb. And it worked?
I believe in some countries in the world, the year goes first, then the month, then the day (2024/08/08 or 2024, August 8). Seems more logical to me than the literal inverse (08/08/2024 or 8 August 2024).
But yeah, the metric system reigns supreme.
I would’ve mentioned it but I forgot what it’s called. Thanks for reminding me.
Year, month, day is the most logical. I’ll stand by month, day, year as being more logical than day, month, year because it’s somewhat more sorted lol.
How in the world is (month/day/year) more sorted than (day/month/year)? I see two use-cases: Sorting things chronologically, in which case you want YYYY/MM/DD, or referring to nearby dates, where the year or even month can be assumed known implicitly, in which case you use DD/MM/YYYY. In no sane world does MM/DD/YYYY make sense.
Because you put big numbers first! Three hundred twenty one is written 321 not 1, 20, and 300. 21 and 300 is more sorted. MM/DD/YYYY only has one element out of place instead of being totally backwards.
Big numbers first is not the only way to sort - look at say how they sort the speeds of runners in a race.
If it is “backwards”, it is sorted, in reverse order. If it has an element out of place it is not sorted.
It’s only when they extend to hh:mm:ss dd/mm/yyyy that it becomes assorted. They need to fully commit and either use tzmm:tzhh+ fff.ss:mm:hh dd/mm/yyyy or just use fucking iso 8601. Fuck everyone who doesn’t; fuck M$, fuck oracle, fuck humans.
Runners use minutes before seconds
Wouldn’t the second one make more sense as an upside down pyramid?
Because the first digit in each of the numbers is larger than the second digit it would be the triple inverted pyramid as shown, where the larger numbers correspond to larger sub-pyramids and larger digits correspond to the larger side of the sub-pyramid.
The colored text and marks on the pyramids are to show that.
I imagined, but I was too lazy to actually look at the colors lol. Thanks for explaining :)
One kilometer is 1000 meters, one meter is 1000 millimeters. One square meter is 1,000,000 millimeters, one cubic meter is 1000 liters.
1 liter of water is 1 kilograms, so 1 cubic meter is 1000 kilograms. Sand is about 2.3 times heavier than water, so 1 cubic meter of sand is 2300 kilograms, or 2.3 metric tonnes.
I’m 1.96 meters tall, or 1 meter and 960 millimeters, or 1 meter and 96 centimeters. I weigh about 85 kilos, or 85.000 grams. Being 65% water, I carry about 55.25 kilograms of water, which will fill a little over 55 one liter water bottles
I can do this all day
Now let’s do the same with imperial units! You first, cuz I’m not going to touch that shit with a 10 foot pole…
One mile is 5280 feet, one foot is 12 inches. One square foot is 144 square inches, one cubic foot is 1728 cubic inches.
1 gallon of water is 8.34 pounds, and 1 cubic foot is 7.48 gallons, so a cubic foot of water weighs 62.38 pounds. If sand is 2.3 times heavier than water, a cubic foot of sand weighs 143.5 pounds.
I am 5 feet 10 inches tall, or 5.83 feet, or 70 inches. I weigh about 220 pounds, or 3520 ounces. If I’m 65% water, I carry about 143 pounds of water, or a little over 16 gallons.
Guh
Bit silly to mix decimal with non-base 10 measurements!
It’s worse than that. Inches are base 12, ounces and cups are base 16, machinists use thousandths of an inch, and surveyors use tenths of a foot!
And computers use base 2. Bastards.
That was totally logical to me
I had to check the math because 1 m2 being 2300 kg while 1 cu ft at 143 lbs seemed crazy, but with the volume difference it’s all correct.
Thank you for putting in the effort 🙃
To illustrate, 1m³ = (100cm)³ = 1,000,000cm³ = (1000mm)³ = 1,000,000,000mm³
You go from the single dimensional conversion between m and cm being a factor of 100 and 1000 for m and mm, to the 3 dimensional conversion being a factor of 1 million for m and cm or 1 billion for m and mm. It scales up fast.
What a great snapshot of life in Canada
This guy/gal specific gravities.
Height in imperial is kinda useful. If you say a person is 4 foot tall vs 6 foot tall it immediately paints a vivid picture
This isn’t some intrinsic value. What you’re used to makes the most sense. If you were used to measuring people’s height in meters, 1.3 meters vs 2 meters would paint just as vivid a picture.
You get used to it. 150cm versus 180cm, since I don’t often meet anybody four foot tall.
Classroom supplies for elementary school always included a 30 cm ruler, so you’d immediately know what 30 cm difference is
Imperial US system is defined using the metric system…
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.
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
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.
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
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.
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.
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.
Metric is just easier and the founders of the US actually considered it but wars -obviously- distracted them from switching to it.
The more I read about America, the more I realise what a fucking stupid country it was, is, and will probably keep on being.
If I could read, I’d probably be insulted by this comment.
Hence the effort to defund education.
As if people weren’t so fuckin dumb already.
Christ WTF year are we fucking in you guys?
There are some pretty smart people in America tho
Indeed, too bad nobody wants to listen to them
And the most ridiculous (or inclusive) thing are tiresizes in Europe (perhaps somewhere else, too?). 195/55r16 195 is the width in millimeters 55 is the height in percentage of the width R16 is the radius of the wheel in inches
Same in US…
The idea that a simpler system of weights and measures that operate in base-10 will somehow cripple America is somehow fucking hilarious.
Uncle Sam couldn’t handle the success the metric system would bring. /s
