What this calculator does
Weight On Other Planets works out how much a mass would weigh on the Moon or another planet, from each body’s surface gravity. 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.
