Weight on Other Planets CalculatorYour weight on the Moon, Mars, Jupiter and across the Solar System
Enter what your scale shows on Earth. See what it would read on every planet and major moon, using NASA surface gravity data.
By Manzoor Ahmad, pharmacist · Updated How do you work out your weight on another planet?
Multiply your Earth weight by the planet’s surface gravity, then divide by Earth’s 9.8 m/s². Someone who weighs 70 kg on Earth would read about 11.6 kg on the Moon (1.62 m/s²), 26.4 kg on Mars (3.7 m/s²) and 165 kg on Jupiter (23.1 m/s²). Your mass never changes; only the pull of gravity does.
The weight on other planets formula
Jump height follows the same logic in reverse. With the same leg power, hplanet = hEarth × (gEarth ÷ gplanet), so lower gravity means higher jumps.
Surface gravity across the Solar System
| World | Surface gravity | × Earth | 70 kg on Earth becomes |
|---|---|---|---|
| Mercury | 3.7 m/s² | 0.38 | 26.4 kg |
| Venus | 8.9 m/s² | 0.91 | 63.6 kg |
| Earth | 9.8 m/s² | 1.00 | 70.0 kg |
| Moon | 1.62 m/s² | 0.165 | 11.6 kg |
| Mars | 3.7 m/s² | 0.38 | 26.4 kg |
| Jupiter | 23.1 m/s² | 2.36 | 165.0 kg |
| Saturn | 9.0 m/s² | 0.92 | 64.3 kg |
| Uranus | 8.7 m/s² | 0.89 | 62.1 kg |
| Neptune | 11.0 m/s² | 1.12 | 78.6 kg |
| Pluto | 0.7 m/s² | 0.071 | 5.0 kg |
Values follow the NASA Planetary Fact Sheet, where gas giant gravity is measured at the 1-bar pressure level. Gravity also varies slightly with latitude and altitude on every world.
Why gravity differs from world to world
Surface gravity depends on two things: how much mass a world has, and how far its surface is from its center (g = GM ÷ r²). That is why:
- Mercury and Mars have nearly the same gravity even though Mars has almost twice Mercury’s mass. Mercury is smaller and denser.
- Saturn feels lighter than Earth despite having 95 times Earth’s mass, because its huge radius puts its cloud tops far from its center.
- Jupiter is the heaviest place to stand among the planets, at 2.36 times Earth’s gravity.
The same mass-and-radius relationship decides how fast a rocket must go to leave each world. See the escape velocity calculator.
Weight on other planets FAQs
Multiply your Earth weight by the planet's surface gravity divided by Earth's: Weight on planet = Earth weight × (g planet ÷ 9.8 m/s²). A 70 kg reading on Earth becomes about 11.6 kg-equivalent on the Moon and 26.4 on Mars.
No. Mass is the amount of matter in you and stays the same everywhere. Weight is the force gravity exerts on that mass, so it changes from planet to planet.
About 16.5% of your Earth weight, roughly one-sixth, because the Moon's surface gravity is 1.62 m/s². A person who weighs 150 lb on Earth would weigh about 25 lb on the Moon.
About 38% of your Earth weight. 150 lb on Earth is roughly 57 lb on Mars, because Mars's surface gravity is 3.7 m/s².
Jupiter. Its gravity at the cloud tops is 23.1 m/s², about 2.4 times Earth's, so 150 lb on Earth would be about 354 lb on Jupiter.
No. The gas giants have no solid surface. Their 'surface gravity' is measured at the level where atmospheric pressure equals 1 bar, roughly where cloud tops are.
Saturn is huge but very low in density, less dense than water. Its large radius means you would stand far from its center, so its surface gravity is only about 0.92 times Earth's.
Weight in newtons is mass (kg) × gravitational acceleration (m/s²). A 70 kg person weighs about 686 N on Earth and 113 N on the Moon.
With the same takeoff speed, jump height scales with 1 ÷ gravity. A 0.5 m jump on Earth would reach about 3 m on the Moon, ignoring the bulky spacesuit.
Planet and Moon values come from NASA's Planetary Fact Sheet. Values for Jupiter's and Saturn's moons come from NASA planetary data. Gravity also varies slightly with latitude and altitude on every world.
Scales measure the force you push down with, then convert it to kilograms assuming Earth's gravity. On Mars a scale calibrated for Earth would show a smaller number even though your mass is unchanged.
About 28 times your Earth weight at the visible surface (photosphere), where gravity is about 274 m/s². Of course, the Sun has no solid surface and is far too hot to visit.
