Weight on the Moon calculator
This weight on the Moon calculator shows what you would weigh there: enter your body weight, pick a world and read the scale reading, the weight force in newtons and your jump height, with every planet compared in one table.
Example: Your weight (mass) 70 kg / lb · Unit: Kilograms (kg) · World: Moon · Jump height on Earth 40 cm → Your weight there: Moon: 70 kg read only 11.6 kg on a scale. Source: NASA – Planetary Fact Sheet (Oberflächenschwerkraft). Updated: .
How it is calculated
Someone who weighs 70 kg on Earth would read only about 11.6 kg on a scale on the Moon, about one sixth. The calculator works this out for the Moon, Mars and every other planet.
How it is calculated
What counts is the gravitational acceleration g at the surface. It is 9.8 m/s² on Earth, 1.62 m/s² on the Moon, 3.7 m/s² on Mars and 23.1 m/s² on Jupiter. Weight force is mass times g; the scale reading is mass times the body's g divided by Earth's g. The values come from NASA's Planetary Fact Sheet.
The tool also estimates your jump height: with the same take-off speed it scales inversely with g. A 40 cm jump here becomes about 2.4 m on the Moon.
Mass and weight
Mass in kilograms is the same everywhere, weight as a force is not. In everyday speech "weight" often means mass, so the table gives both: the reading of an Earth scale and the force in newtons.

Frequently asked questions
How much would I weigh on the Moon?
About 16.5 percent of your Earth weight, a little over one sixth. At 70 kg a scale on the Moon would show about 11.6 kg.
How much would I weigh on Mars?
About 38 percent. 70 kg becomes roughly 26 kg on a scale on Mars.
Why is weight lower on the Moon?
The Moon has less mass and a smaller radius than Earth, so it pulls less: 1.62 instead of 9.8 m/s². Your mass stays the same, only the weight force drops.
Where would I weigh the most?
On Jupiter, at about 236 percent of your Earth weight if you stood at the cloud tops. At the Sun's visible surface it would be almost 28 times.
How high could I jump on the Moon?
About six times as high as on Earth with the same effort. A 40 cm jump here would be roughly 2.4 m there, though a spacesuit limits it in practice.
