What this calculator does
Paper sheet & ream weight works out weight of a sheet or a stack of paper from its GSM and dimensions. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaSheet weight (g) = GSM × width (m) × height (m); Stack weight = sheet weight × sheet count
