About the Weight Calculator
The Weight Calculator converts values between common weight units and shows how the same mass weighs differently under other gravity. Enter a number, pick the units, and you get an instant conversion or the adjusted weight for a chosen gravitational field.
For gravity variations it applies the standard formula W = m × g, where mass stays constant and the gravitational acceleration g changes. Unit conversions rely on fixed factors, such as 1 kilogram equal to 2.20462 pounds. You provide the mass, the input unit, and either a target unit or a celestial body like the Moon or Mars. Tip: keep track of mass versus weight, since a result in newtons measures force while kilograms measure mass.
- Enter your value in the weight field.
- Select the input unit and the unit or planet you want.
- Read the converted result and compare values if needed.
