User Guide

The mass of an object never changes but the weight will vary depending on the gravitational pull acting on it.

Use this calculator to determine the weight of an object from its mass and the acceleration due to gravity at a particular geographical location or any other source of gravitational attraction.

Formula

The calculation formula used for this tool is:

Fg = m · g

Symbols

• Fg = weight or force due to gravity of object
• m = mass of object
• g = local gravity (e.g. standard earth gravity or g0 = 9.80665ms-2)

Mass of Object

Enter the mass of the object that you wish to determine the gravitational weight.

Acceleration Due To Gravity

Enter the acceleration due to gravity for your geographical location in metres per second per second (ms-2) or feet per second per second (fts-2).

The local gravity on earth is dependent on several factors such as latitude, height above sea-level, local geological density, etc… refer to your national geological survey data for your location or use this local gravity calculator to determine a close approximation. The default value is set to 9.80665 ms-2 which is the standard acceleration due to earths gravity.

You can also enter acceleration due to the pull of gravity for other places in the solar system such as Mars (3.71 ms-2), Moon (1.62 ms-2),  Titan (1.35 ms-2)  or Europa (1.31 ms-2) for example.

Weight

This is the force generated by the pull of gravity acting on the object.
