No, its the basis of paper weights too, which are measured in grams/m^2

Ok, that's revelation of the day! (sometimes you fail to connect the simplest things). Now I can eyeball the weight of a stack of paper :-)

Another thing that the US fails miserably at. 80# cover, 110# index, 24# bond … it’s all meaningless.

Those numbers aren't meaningless. They're the weight of a ream (500 sheets) of that paper at 17x22.
