I don't think that's the reason Gary.
If I remember correctly from my army days, The AK-47 used ever so slightly
larger ammo than our M16. As a result, they could use our ammo in their
rifles, granted with a little less precision, but we could not use their
ammo in ours.
I don't think the decision was based on tools.
Most likely, like most everything else, there was a lobby behind that
decision.
IMO it was a BIG mistake not to go to the same system the rest of the world
uses.

It was once explained to me that the uS refuses to switch more for military
reasons than any other.
By having all BSA parts and fittings, the tool used by an adversary would
not properly fit, nor would any so-called standard replacement parts.
As far as Kg as a weight unit, you are correct, it is a mass unit,
equivalent to 2.2 pounds at standard elevation and conditions.
For most important measurements, the mass is more important than the weight
(as in purchasing a gram of Gold).
Torque is still in force-length units such as foot-pounds, ounce-inches,
Newton-meters and so on.

Americans using pound for a unit of mass and a unit of force. The only
saving grace is that 1 kg (1 lb) mass weighs 1 kg (1 lb) force on earth, at
sea level. Still, the introduction of a constant to Newton's famous equation
is a pain.
