Don't forget the most important US measurements of them all: 5.56, 7.62, 9, etc.
-
.308
Oh wait....
-
.308 is 7.62, civilian measurement vs military (there's actually implications related to pressures, sidewall thicknesses, machining tolerances, but yeah same same)
-
Yeah, it's generally safe to shoot 7.62 from a 308-chambered gun, but not the other way around.
-
Same for 5.56 and .223.

pls explain 🙂
-
.308 is caliber in inches thus not metric.
-
why do they use decimal for imperial units?
-
Because even people who worked in imperial recognized that dealing with stupid fractions is stupid.
-
I have a 77/250 rifle at home because I’m a real American.

It means the round fired by the gun is .308 inches in diameter, or 7.62mm. Gun caliber is measured in inches for Imperial.
-
Because they couldn't rationalize using fractions.
-
Machining is often done in thousandths of an inch.
-
so why don't they write 1/1000 in then?
-
Because, unlike internet pendants, machinists have shit to do.
