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.
This online tool will also display a conversion scale that automatically refreshes to relate to the current values and units selected.
The calculation formula used for this tool is:
Fg = m x g
- Fg = weight or force due to gravity of object
- m = mass of object
- g = local gravity (e.g. standard = 9.80665ms-2)
Mass of Object
Enter the mass of the object that you wish to determine the gravitational weight.
Local Gravity acting on Object
Enter the acceleration due to gravity for your geographical location in metres per second per second (ms-2). The local gravity 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 standard gravity.
Weight of Object
This is the force generated by the pull of gravity acting on the object mass.
