For a given type of paper, the computations are about similar on both
sides of the Atlantic:
At 75g/m2, what's the weight of an A4 piece: 75/2^4 = 4.51g.
At 20lb, what's the weight of an 8.5 x 11 piece: 20 * 16 / (4 * 500) =
0.16 oz = 4.536 g.
Of course, you have to know that the "20lb" is the weight of 500 sheets
of 17x22 paper (and that there are 16 oz in a lb). But if you multiply
all the constants, you simply need to remember that the paper weight
multiplied by .008 gives the weight of the paper (in onces).
The bad news is that the multiplier depends on the type of paper
(because different sheet sizes and number of sheets are used depending
on the type). You can take care of that by remembering that 20 lb bound
~ 50 lb offset ~ 28 lb cover ~ 46 lb tag ~ 42 lb index ~ 75 g/m2. Isn't
