How much does 20-pound bond paper weigh?
The metric system has a much better way of measuring paper. A0 paper is a square meter of paper. One side is 84.1 centimeters long and the other is 118.9 centimeters (the longer side’s length is the square root of 2 longer than the shorter side’s length). A1 paper is half of an A0 sheet (preserving the square root of 2 rule). A2 is half of an A1 sheet, and so on. And paper weight is measured in grams per square meter, so it is very easy to figure out.
