Choose a calculation for weight W, mass m or gravity g. Enter the other two values and the calculator will solve for the third in your selected units.
Weight Equation used in this calculator:
\( W \) = weight
\( m \) = mass
\( g \) = gravity (acceleration due to gravity)
The Weight Calculator uses the formula W = mg, or Weight (W) is equal to mass (m) times gravity (g). The calculator can use any two of the values to calculate the third. Along with values, enter the known units of measure for each and this calculator will convert among units. Weight is a force and gravity is the acceleration due to gravity where W = mg is a special case of F = ma.
Solving for weight, mass or gravity we use the following formulas:
Calculate W Given m and g
Calculate weight given mass and gravity.
Calculate m Given W and g
Calculate mass given weight and gravity.
Calculate g Given W and m
Calculate gravity given weight and mass.
Use the following reference table if you need gravity of a specific planet.

*Standard gravity (gn). 1.00gn is equal to 9.80665 m/s2, gravity on Earth.
