Ask anyone using advanced math in engineering which is still generally dominated by the inch
I did two years of it, and it had about as much to do with inches (or for that matter, metres) as duck feathers have to do with philosophy.
as is reloading.
57.5 grains of IMR 4350 equals 3.725 grams. Now having never seen a reloading scale in grams though I believe they exist which would you rather measure out on a beam balance scale? I admit the electronic scales would solve any issues but still you are looking at 4 numbers and a decimal point instead of three.
The fourth significant figure on your measurement in grams would mean that it is theoretically to a greater degree of precision. However, the typical beam balance is not actually capable of that level of precision, so it is rather spurious. Render it as 3.73 g and you are within a margin less than the resolution of a typical reloader's scale of your 57.5 gn. FWIW I throw all of my charges anyway, and use a metric measurement. It works.
