OK, MIL isn't totally to metric. You can do it if you want, but it isn't necessary.
Klem used MILs because he grew up using metric and thinks in metric. And because its a better system.
But MIL doesn't mean millimeter. It means milliradian. As in 1/1000 of a radian, which is a metric unit.
MILS = easier math, because it based on 10 no matter what measuring system you used, instead of MOA.
That is why MILS dominate Long Range Shooting and the scopes designed for it.
It started with the military usage of mil dot scopes, then evolved from there.
Before our current age of smartphone apps that can give you your drops automatically, or even electronic calculators, it was necessary once you knew your drops and distance to calculate how much correction was needed. Those calculations are easier and more accurate when using MILS.
This applies if you operate in a world where you are shooting at various distance targets, as in the military or in competition or hunting and need to be able to rely on mathematics instead of an electronic device.
However, if all you are doing is shooting at a few known distance targets, then it largely doesn't matter as long as you:
1) have a scope with matching units on target and reticle, MIL/MIL or MOA/MOA. This really isn't a problem anymore unless you pick a scope manufactured by morons.
2) know your distance.
3) know your drops.
I standardized on MILS when I started to shoot long range and wanted to be able to range and hold over easier and have the widest selection of quality scopes.
Read this link. I grabbed a bunch of stuff here, but it explains a bit better.
