Well you know, first things first.

And by "Americans" you mean the companies that manufacture the firearms, right? Or whatever body, if any, that controls what size ammunition cartridges are measured by?

Both are used. If you see caliber after the number it's in 100 of an inch. If you see mm it's metric. (Though caliber refers to barrel diameter and can be expressed in imperial or metric). So a 45 caliber is 0.45 inches or about 11.5mm.

NATO has standardised on a few round types so they can share supplies between countries. The NATO 7.62×51mm round is very similar to the .308 and they can usually be interchanged.
