I am curious about one thing: does the U.S. army use the metric system?
The U.S. "officially" uses metric. But to the average day to day things imperial is used. About the only metric I can use is somewhat meters for distance when shooting. And to show when among just U.S. the ruck marches are in miles 12 and 25 being the big two I have been in, never finished the second one though. So personally I mix in just meters, not centimeters or kilometers, to my measurements and likely the only reason I can do that reasonably well is how close it and yards are.
