Weight on other planets calculator

How it works

Enter your weight on Earth to see what a scale would show on other planets and the Moon.

The formula

Weight elsewhere = Earth weight × (that body's surface gravity ÷ Earth's 9.81 m/s²). Your mass does not change.

Worked example

70 kg on Earth reads about 70 × 0.165 ≈ 11.6 kg on the Moon and about 70 × 0.38 ≈ 26.5 kg on Mars.

Good to know

• Gas giants have no solid surface; their figure uses gravity at cloud-top level.
