We only measure some calibers in metric. Some we measure in decimals of an inch: .380, .357, .223, .308, .50 BMG.
And the really fun ones have both the caliber and powder charge as one name: 45-70, 30-30, etc.
And because fuck you shotguns use gauge. A unit so mindbogglingly archaic it gives me an anurism. And then the British starts with fucking weight for their pieces....
