Oh god this is what we mean
Oh just wait until you see imperial hex screws. In metric you get them in screwdriver size relating to mm. US hex screws are like 16/64 of an inch or 5/16 of an apple. And of course they don't relate to metric at all and you can't use the same tools.
Or fucking AWG. Higher number means smaller diameter wire, and Americans are afraid of decimal or negative numbers so large diameters are 00, 000 etc. The formula is batshit insane
so people just use a lookup table.
Gauge is historically number of passes through gauging machine. With the machine and material in question being different for every single one. We took that and put it to a standard, so it's super messy and makes no sense.
Well, I wonder what kind of gauging machine can do -3 passes for 0000 wire... /s
Too bad AWG is so ubiquitous it's starting to creep into Europe.
