In my other life in the paper industry, the US measure the weight per surface area of paper in pounds per ream (now generally 500 sheets) where the specified sheet size depends on the type of paper you are taking about. So 20lb newsprint (36×24 inches) is much lighter than 20lb bond paper (22×17 inches) for example !
