See what you would weigh on the Moon, Mars, Jupiter and every other world in the solar system.
Multiply your Earth weight by 0.165. A 70 kg person weighs about 11.6 kg on the Moon, 26.5 kg on Mars and 177 kg on Jupiter on a scale calibrated for Earth.
Your mass is the same everywhere, but your weight depends on the gravity of the world you stand on. Enter your mass and this calculator shows your weight on Mercury, Venus, Earth, the Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and the Sun's surface — as a force in newtons and as the reading a bathroom scale calibrated on Earth would show.
It is a fun way to learn about gravity and a handy teaching aid. To work backwards from weight to mass see the Mass Calculator.
Weight is mass times gravitational acceleration.
| Body | Surface gravity | Weight (force) | Scale reads |
|---|---|---|---|
| Mercury | 3.7 m/s² | 259 N | 26.41 kg |
| Venus | 8.87 m/s² | 620.9 N | 63.31 kg |
| Earth | 9.807 m/s² | 686.47 N | 70 kg |
| Moon | 1.62 m/s² | 113.4 N | 11.56 kg |
| Mars | 3.71 m/s² | 259.7 N | 26.48 kg |
| Jupiter | 24.79 m/s² | 1,735.3 N | 176.95 kg |
| Saturn | 10.44 m/s² | 730.8 N | 74.52 kg |
| Uranus | 8.87 m/s² | 620.9 N | 63.31 kg |
| Neptune | 11.15 m/s² | 780.5 N | 79.59 kg |
| Pluto | 0.62 m/s² | 43.4 N | 4.43 kg |
| Sun (surface) | 274 m/s² | 19,180 N | 1,955.82 kg |
Mass is the amount of matter in your body. Weight is the pull of gravity on that matter. On the Moon your mass is unchanged, but gravity is about one-sixth of Earth's so you feel much lighter. Gas giants and the Sun have no solid surface; their values are given at the visible cloud tops or surface layer.
About 16.5% of your Earth weight, because lunar gravity is 1.62 m/s² compared with 9.81 on Earth.
About 38% of your Earth weight, since Mars's gravity is 3.71 m/s².
On the Sun's surface (about 28 times Earth weight), or among the planets on Jupiter (about 2.5 times).
No. Mass is the amount of matter and does not change; weight is the gravitational force and varies by location.
The number a bathroom scale calibrated on Earth would display if you stood on it on that world.
The force of gravity on your mass: mass × gravity. On Earth, a 70 kg person has a weight of about 686 N.
Yes — choose pounds, stone or grams as the unit of mass.
The Sun's mass is enormous, giving a surface gravity of 274 m/s², about 28 times Earth's.
No — Jupiter has no solid surface. The value is for the cloud tops at the 1-bar level.
