Oh look at that, easy to convert volume to mass measurement.
What's a gallon weigh in lbs? who the fuck knows.

There's a reason why we have both C and K, but they're both the same "scale".

what's 1 litter of water weigh? 1 kg

Probably one of the best Twitter threads I've ever read:

After reading it all, you'll find it pretty strange that we've been using a unit of mass which is actually not perfect. For example:
-one second = the time it takes an electron in a cesium-133 atom to oscillate 9,192,631,770 times (a constant),
-one meter = the distance light travels in a vacuum in 1/299,792,458 of a second (another perfect constant), etc.
BUT the one kilogram is surprisingly equal to the mass of a physical artifact stored in a vault in France (called the International Prototype Kilogram, the IPK); I'm finding it hard to believe:
This thing is not constantly remaining the same! See the reason here. The mass of 1 kg is literally losing its mass over time!
Kilogram never made any *good* sense but we've been using it for hundreds of years, just like fiat never made any sense but is still being used even after all this time.
