Because it is a special kind of paper material, its thickness and therefore the weight calculation,

the number of grams units generally refers to the weight of the number of grams per square meter,

general writing paper 70 g, 80 g, coated paper 128 g, 157 g two sizes, note that this is not a ran

ge, not the 128 to 157, but that these two specifications, packaging paper generally 200 grams or 250

grams,a little heavier packaging paper products of greater thickness, typically 450 g, 500 g and so on.

not mentioned in the concept of everyday life, but rather a full paper. A ream equals 500 sheets of

paper,which is 500 full paper. As tonne, depending on the type of paper, each paper is not the same

thickness,so the final number of sheets of paper per ton are not the same, so Zhang, so with tons and
