How come people say 5,000 km and not 5 Mm?
why not just say millions of meters or Mega meters?

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.
