I agree with Foxx. Clicks and subtensions in consistent units.

By the way, MRAD is neither metric in terms of units of distance (yards versus meters, inches versus centimeters, etc...).

It is metric in that the math is primarily units of ten.

With your target set at a distance of 1000 units of length, adusting your scope 1 MRAD moves your point of aim 1 unit.

So for example, at 1000 yards, 1 MRAD projected on a target is 1 yard, at 1000 inches, 1 MRAD projected on a target is one inch, at 1000 light years, 1 MRAD projected on the target moves your point of aim 1 light year (but calculating bullet drop for that distance is a real bear.)
