The tonnage or poundage of a quantity of paper. The weight of paper may be expressed as basis weight, ream weight, M weight, or grammage. Basis weight is the weight in pounds of 500 sheets of paper cut to a given standard size (called basic size), such as 25x38, depending on the grade of paper. Ream weight is the actual weight in pounds of 500 sheets of paper, regardless of basic size< of grade. M weight is the actual weight of 1,000 sheets of paper. Because this is twice the quantity of a ream of paper, it is also twice the ream weight. Grammage is a metric measure similar to the basis weight of paper. Unlike basis weight, which uses different basic sizes for different grades of paper, grammage always uses the same sheet size one square meter regardless of the paper grade. See also actual weight, basis weight, M weight.
