I’m not trying to be rude here, but the math is not my problem, I understand dimensional analysis.

After doing that calculation, is it likely that you are going to mistake the term “percent” and “mg”, or after doing something so specific with units are you more likely to use the right one?

I’m saying that if OP actually did any of this (you say their math is on point but they didn’t do any haha) they’d probably be using the correct term rather than the incorrect yet common “street” term
