Surface Gravity Calculator

Want to know what the surface gravity is on any celestial object? You just need to know it's mass in terms of Earth masses (e.g. Earth = 1, Venus = 0.815, Mars = 0.107 etc.) and it's radius. This calculator will do the rest.

Radius of your planet km e.g. Earth=6378
Planetary Mass express in Earth masses = e.g. Earth=1, Venus=0.815

Result:

The result shows the gravity in terms of Earth gravities (1 Earth gravity = 1g).
A result of 1 gravity = 1 Earth gravity, or put another way 100% Earth gravity
A result of 1.5 gravity = 150% Earth gravity

This function is included in Orbital Calculator, where it automatically calculates this when displaying object data (in the menu item Gravitational Masses/Manage)
