How the Weight on Other Worlds Calculator works

Your mass stays the same everywhere, but your weight changes with the surface gravity of each world. Weight there = Earth weight × (gravity there ÷ Earth gravity). Surface gravity is 0.165 of Earth on the Moon, 0.379 on Mars, and 2.53 on Jupiter at the cloud tops. Gas giants and the Sun have no solid surface, so their value applies at the visible top layer. Example: with Your weight on Earth 70 kg and World Mars, the result is Your weight there (kg-force) = 26.53; Your weight there (lb) = 58.49; Surface gravity (m/s²) = 3.72.
