What I don't understand is why bother using yards in the first place. Since human beings are very poor judges of distance, we all use laser range finders. Since you reckon a mil is a mil..., why not reason the same way with meters & yards. Since nobody could judge 500 yards from 500 meters, why not simply set the range finder to meters & be done with it.
I dont give a rats ass meters or yards other than meters are divisible by ten & have SI units to use.
I don't know why anyone would continue with a such a backward, busted ass measurement system let alone try to twist it in with metric system.
