How much would you weigh on other planets?
Enter a weight and instantly see what a scale would show on all 8 planets, the Moon, Pluto, and the Sun. The factors come from NASA's planetary fact sheet. Why only the reading changes — and not you — is explained in our article on mass and weight.
Enter any weight — yours, your cat's, your suitcase's.

Your mass never changes — only the pull on it does. A scale measures that pull.
Example: a 70 kg (154 lb) person across the solar system
| Body | Gravity vs. Earth | Scale reading |
|---|---|---|
| Sun (cloud tops) | ×28 | 2 t (2.2 tons) |
| Mercury | ×0.378 | 26 kg (58 lb) |
| Venus | ×0.907 | 63 kg (140 lb) |
| Earth | ×1 | 70 kg (154 lb) |
| Moon | ×0.166 | 12 kg (26 lb) |
| Mars | ×0.379 | 27 kg (58 lb) |
| Jupiter (cloud tops) | ×2.36 | 165 kg (364 lb) |
| Saturn (cloud tops) | ×0.916 | 64 kg (141 lb) |
| Uranus (cloud tops) | ×0.889 | 62 kg (137 lb) |
| Neptune (cloud tops) | ×1.12 | 78 kg (173 lb) |
| Pluto | ×0.071 | 5 kg (11 lb) |
How much would I weigh on the Moon?
About a sixth of your Earth weight — the Moon's surface gravity is 0.166 of Earth's (NASA). A 70 kg (154 lb) person would read 12 kg (26 lb) on a scale. Your mass stays the same; only the pull on it changes.
How much would I weigh on Mars?
A bit over a third of your Earth weight: Mars pulls with 0.379 of Earth's surface gravity (NASA), so a 70 kg (154 lb) person reads 27 kg (58 lb).
How much would I weigh on Jupiter?
About 2.36 times your Earth weight — 165 kg (364 lb) for a 70 kg (154 lb) person. But Jupiter is a gas giant with no surface to stand on: the value applies at the visible cloud tops (NASA fact sheet, equatorial value including rotation).
Guessing planet gravity is easy — guessing what things weigh on Earth is the real game.
