Surface Gravity Calculator

Calculate the surface gravity of a planet using its mass and radius.

Formula:

Surface Gravity (g):

g = G × Mass / Radius²

Where:
g = surface gravity (m/s²)
G = gravitational constant = 6.67430 × 10⁻¹¹ m³·kg⁻¹·s⁻²
Mass = mass of the planet (kg)
Radius = radius of the planet (m)
