Why call Imperial Units the American system? It’s the British Empire’s fault. And the UK still uses it. Like so much they say weird ass shit like “I weigh 12 stones.”
Doesnt the UK use a mix of both? Same as Canada?
US Customary Units and Imperial Units are not 100% the same, so three former the American system makes sense.
My favourite part of the metric system is that with it’s water weight being 1-1 with volume; measuring liquids is super easy with a scale.
Liquids as in water specifically and not other liquids.
a gallon of water boils in 10 minutes on a whirlpool electric range in turbo mode
When I learned the consistency (synergy?) between metric measures, I thought that was so amazing.
In the olden days sciencey types and engineers kept fact books listing such relations. They had a specific name that escapes me.
Before handheld calculators, they also kept books of pre-calculated mathematical operations, so they were used to having numbers books around.

Likely a “CRC”: CRC Standard Mathematical Tables, which is probably the same book as the pre-calculated mathematical operations you mentioned. It has a lot of good mathematical stuff in it such as basic formulas, trig functions, log tables, integral and differential functions, and formulas up through around Fourier analysis.
If we were doing that thought exercise where you can take a “go bag” back in time to build science up more quickly, a CRC and a slide rule would probably be in mine. I’d probably throw in a prism and as compact of a microscope that uses a mirror as a light source as I could get away with; both for showing small stuff living in water and for showing what couldn’t be manufactured yet (depending on when I went back). I wouldn’t waste space in the bag for anything dealing with the imperial system.
Grateful for my blessings and blessed to give back, I’m giving 35 grand to anyone who messages “GRACE” on Telegram @Georgestones12, I understand that many people are struggling with bills, and I want to help reduce that burden. It’s a season of love, kindness, and blessings.
One mole of hydrogen-1 isn’t 1 gram because of the binding energy of protons and neutrons. One mole of hydrogen-1 is about 1.008g
You know that water being exactly 1kg and 1l is specific to one pressure and temperature combination?
Mole is a number of particles, not a volume. A mole of hydrogen-1 will always have the same mass regardless of temperature or pressure
The point is that you do not have that precision. But it absolutely is good enough for pretty much everything. A 0.8 % error is often well below measurement error. Like in any mass balance in a chemical system, say a refinery or whatever. You can ignore argon and all other gases except N2 and O2 in air for the same reason in almost every application.
But even if we apply the same logic, 1.008 is “incorrec” too, it is 1.00794.
And that is incorrect too, not because of higher precision, but because of binding energy. Two separate hydrogen atoms (2 H) have slightly more mass than one hydrogen molecule (H₂) because forming the H–H chemical bond releases energy, reducing the system’s mass according via E= m*c² That extends to every single compound. They all have different atomic masses in them.
I think the point is made.
Wild Thing by Josh Bazell, in case anyone was wondering what book that is.
Found out recently that a fluid ounce of water doesn’t weigh an ounce, and that makes me mad
A pints a pound
I think that’s all we got
Unfortunately, due to inflation, a pint is usually minimum £5, if you’re in London then expect it to be heavier.
This is how I found out that Americans don’t even have full pints.
The UK doesn’t want to give up pints of beer because they’re bigger than a half liter.
American ones are smaller.
Just get me a liter’o’cola or there will be hell to pay!
Getting these two after eachother is fate
We need to go deeper, america needs to come up with new time measurements too. Everything must go!
I want this but with diet coke.

Huh. I must have missed this book in A Series of Unfortunate Events.
Did she undelete her account?
which one are you referring to?
Violet. She used to hornypost
How unfortunate
True except for calorie. Metric typically uses Joules, which is good because it’s just the product of force (N) and distance units (m), instead of requiring a conversion factor.
If by “metric system,” you mean SI. But then, SI uses m3 for volume, not litres. The author didn’t specify which metric system, so this could be valid.
1m3 = 1 kiloliter so maybe they use both
Having read a good portion of the comments in this thread and the anti-american sentiment attached, I am convinced that the only reason the US isn’t wholly metric at this point is out of spite.
I know the actual reason is that it would cost too damn much to convert all the infrastructure we’ve built in imperial, but now I just want the USA to keep kicking everyone in the balls at the Olympics, in the military, and with global corporate supremacy just to own it to the world that they’re better than all of you AND they use imperial.
Not using the metric system is such a massive waste of money (let’s talk about international trade, everyone else uses metric), there’s no way anyone is justifying it based on cost. It’s because when they actually tried to adopt the metric system in the 70’s people revolted and destroyed all the new signs. Because this is a barbaric fuckin country.
Most of the US standard units these days are defined in terms of metric units. But lots of individual laws and regulations from the federal down to the state, county, and municipal level are still worded in terms of those US standard units. This means that ultimately the U.S. is already using the metric system in actual fact, while the US standard units are used in name only. For example, the U.S. Standard foot is common throughout the country to define the boundaries of real property (land), but since 1959 1 foot has been defined as equaling 0.3048 meter exactly. The US foot is set to be replaced soon with the international foot, similarly defined by the meter, when the National Geodetic Service finalizes it’s new datums and state plane coordinate systems.
Point is, the US is already using the metric system, with a heavy accent.
Imperial is just social inertia
Hahaha yes you guys are the number one 😂
Lots of industries in USA are metric and keeping the imperial around for the social inertia.
For engineers/scientists this works. For normal people, this works IFF there’s a gradual change. Eg: every sign that’s replaced should have both units. Every product needs to add both units in within next X years. Then they can make imperial optional after a decade or more of common signs and finally go all in on SI.
But ofc no one likes a working solution. They’d rather stick to the measurement system that escaped pirates
