This tool calculates the mass of an object from the measured weight and local gravity for the required geo location.
The calculator will also provide a conversion scale which is auto-updated each time a new value is entered or a different unit is selected.
The calculation formula used for this tool is:
m = Fg / g
- m = mass of object
- Fg = weight or force due to gravity of object
- g = local gravity (e.g. standard = 9.80665ms-2)
Weight of Object
Enter the weight (force) due to the pull of gravity on an object.
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.
Mass of Object
This is the mass of the object, and is independent of location and the influence of gravity.
