What a scale would read on every planet, the Moon and Pluto, using NASA’s surface gravity ratios, plus how high you could jump
Updated October 2026
Weight elsewhere = Earth weight × gravity ratio. For Mars, 150 × 0.377 = 56.55, shown as 56.6 lb. The ratios are NASA’s surface gravity for each body divided by Earth’s 9.8 m/s². Your mass, the amount of you, is the same everywhere; what changes is how hard the planet pulls on it, which is what a bathroom scale measures.
| World | Gravity (Earth = 1) | Gravity (m/s²) | 100 lb person | 150 lb person | 70 kg person |
|---|---|---|---|---|---|
| Mercury | 0.378 | 3.7 | 37.8 lb | 56.7 lb | 26.5 kg |
| Venus | 0.907 | 8.9 | 90.7 lb | 136.1 lb | 63.5 kg |
| Moon | 0.166 | 1.6 | 16.6 lb | 24.9 lb | 11.6 kg |
| Mars | 0.377 | 3.7 | 37.7 lb | 56.6 lb | 26.4 kg |
| Jupiter | 2.36 | 23.1 | 236.0 lb | 354.0 lb | 165.2 kg |
| Saturn | 0.916 | 9.0 | 91.6 lb | 137.4 lb | 64.1 kg |
| Uranus | 0.889 | 8.7 | 88.9 lb | 133.4 lb | 62.2 kg |
| Neptune | 1.12 | 11.0 | 112.0 lb | 168.0 lb | 78.4 kg |
| Pluto (dwarf planet) | 0.071 | 0.7 | 7.1 lb | 10.7 lb | 5.0 kg |
Two surprises: Mercury and Mars have almost the same gravity even though Mars is about twice as massive, and Saturn, 95 times Earth’s mass, would weigh you slightly less than Earth does.
Surface gravity grows with a planet’s mass and shrinks with the square of its radius, because the surface is farther from the center. Dividing NASA’s mass ratio by the square of its diameter ratio comes close to the listed gravity:
| World | Mass (Earth = 1) | Diameter (Earth = 1) | Mass ÷ diameter² | NASA gravity ratio |
|---|---|---|---|---|
| Mercury | 0.0553 | 0.383 | 0.377 | 0.378 |
| Mars | 0.107 | 0.532 | 0.378 | 0.377 |
| Moon | 0.0123 | 0.2724 | 0.166 | 0.166 |
| Jupiter | 317.8 | 11.21 | 2.529 | 2.36 |
| Saturn | 95.2 | 9.45 | 1.066 | 0.916 |
| Uranus | 14.5 | 4.01 | 0.902 | 0.889 |
Mars is twice Mercury’s mass but also wider, and the two effects cancel. For the giant planets the simple estimate runs high because NASA quotes gravity at the equator, where fast spin flings you outward a little and the planet bulges, putting you farther from the center. Jupiter’s own fact sheet gives 23.12 m/s² at the equator and 27.01 m/s² at the poles, so you would weigh about 17% more at a pole than at the equator.
Jupiter, Saturn, Uranus and Neptune are mostly gas and liquid. NASA gives their gravity at the height where the air pressure equals 1 bar, about the pressure at Earth’s sea level. A person there would be floating in clouds, not standing, so treat those weights as what a scale would read at that height.
With the same push off the ground, jump height is inversely proportional to gravity. A 20-inch jump on Earth becomes about 53 inches on Mars and 120 inches on the Moon, but only 8.5 inches on Jupiter. You would also come down more slowly, since the same weak pull sets the speed of the fall.
It uses one gravity value per world. Real gravity varies a little with latitude, altitude and local geology, and orbiting astronauts feel weightless because they are falling around Earth, not because gravity is gone. Your age on each planet is on the companion age calculator.
