But only in regards of nuclear bombs. Maybe it’s because of the scientific origins of these fields. Probably the same reasons why Americans measure firearm munition in mm.
Firearm’s ammunition is a mixed bag because many military sizes are standardized with the rest of NATO. 5.56, 7.62, and 9 mm sure; but then you get a bunch measured in caliber .308, .45, .50.
Familiarity I guess. Mega isn’t really a widely used prefix outside of computers. We even say tons instead of megagrams.
megaton, megawatt, megapascal, megacandela (for military flares), megahertz, megajoule, megaohm, megabequerel
Megatron
And yet we say megatons.
Instead of teragrams.

I’ve only recently gotten my foid card and am learning to shoot and that shit confuses me so much.
and the old gauge system for shotguns.
And 7.62 is just .30 caliber rebranded
To be fair, mass is weird because the base unit is kg (yes, the name includes a prefactor). I have no idea how they managed to fuck it up that badly.
