Calculation Formula

g = G * (M / r²)

Where:
g = surface gravity (m/s²)
G = gravitational constant (6.67430 × 10⁻¹¹ N⋅(m/kg)²)
M = mass of the celestial body (kg)
r = radius of the celestial body (m)

How to Use the Calculator

  1. Enter the mass of the celestial body in kilograms (kg).
  2. Enter the radius of the celestial body in meters (m).
  3. Click the "Calculate" button to compute the surface gravity.
  4. The result will be displayed in meters per second squared (m/s²).

Working Principle

The surface gravity of a celestial body is determined by its mass and radius. The formula used is:

g = G * (M / r²)

Where:

  • g is the surface gravity
  • G is the gravitational constant (6.67430 × 10⁻¹¹ N⋅(m/kg)²)
  • M is the mass of the celestial body
  • r is the radius of the celestial body

This calculator provides a simple way to determine the surface gravity of planets, moons, asteroids, and other celestial bodies by inputting their mass and radius.
