Know how much you would weigh on different celestial bodies in our solar system. By simply entering your weight on Earth, the calculator instantly provides your equivalent weight on the Sun, Moon, planets, and even Pluto.
Sun
g ≈ 27.94 × Earth’s
Mercury
g ≈ 0.377 × Earth’s
Venus
g ≈ 0.904 × Earth’s
Moon
g ≈ 0.165 × Earth’s
Mars
g ≈ 0.378 × Earth’s
Jupiter
g ≈ 2.528 × Earth’s
Saturn
g ≈ 1.064 × Earth’s
Uranus
g ≈ 0.886 × Earth’s
Neptune
g ≈ 1.137 × Earth’s
Pluto
g ≈ 0.063 × Earth’s
How Does This Work?
Your weight on another body is your Earth weight multiplied by the surface gravity factor (g_body / g_Earth). Surface gravity depends on the body’s mass and radius via Newton’s law: g = GM / r², where G is the gravitational constant, M is mass, and r is radius.
