This tool calculates the mass of an object from the measured weight and local gravity for the required geo location on earth or any other source of gravitational pull.
Formula
The formula used by this tool to calculate the mass of an object from the force generated due to pull of gravity for this tool is:
m = Fg / g
Symbols
- m = mass of object
- Fg = weight or force due to gravity acting on an object
- g = local gravity (e.g. standard earth gravity or g0 = 9.80665 ms-2)
Weight
Enter the weight (force) due to the pull of gravity acting on the object.
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.
Mass of Object
This is the mass of the object, and is independent of location and the influence of gravity.
