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. (John Bazell)
Unfortunately converting 1 calorie to joules ruins everything 4.2J per calorie. Makes it annoying to calculate how quickly you can boil water for instance.
A BTU (British thermal unit) is the energy required to raise 1lb of water 1 degree Fahrenheit…which may actually be even dumber, since it’s temperature sensitive to begin with. Dumbest of all, the Brits don’t use that unit very often. The US, and, I assume, Liberia use it all the time.
To Europeans who use German industry norm paper: that’s DIN A2
Some people will use some letter salad just to avoid the imperial system /s

Iirc the Joule is favoured over the Calorie in the SI system.
Is that something people wonder about? I doubt it.
As someone with both solar panels and a water kettle I promise you this is something I frequently wonder about!
It’s not like physicists, chemists or engineers are a thing.
They are in fact 3 things
I’m glad you admit yourself it’s not a thing

Oh, I love these freedom units
Don’t imperial have like 3 different letter sizes depending on the country?
From what I have found, the US has 216mm × 279mm while Canada has 215mm × 280mm which is close enough.
thats A4 bro
Looks like she’s holding A3, not unless she’s absolutely tiny.
A3. Not A2.

Being corrected on a German industry norm, how does that feel? A little ironic, maybe?
Oh schnapps!
