📘 About the Weight on Planets
Your mass is the same everywhere, but your weight depends on gravity. This calculator multiplies your mass by the surface gravity of a planet or moon, W = mg, to give your weight there in newtons.
It also shows what an ordinary bathroom scale (which is calibrated for Earth) would read: on the Moon a 60 kg person would see about 9.9 kg.
🧮 Formula
Gas giants (Jupiter, Saturn, Uranus, Neptune) have no solid surface; their g is quoted at the cloud tops.
✏️ Worked examples
60 kg on the Moon
You get| Weight there (N) | 97.2 |
| A scale would read (kg) | 9.91164 |
| Gravity compared with Earth (×) | 0.165194 |
| Weight on Earth (N) | 588.399 |
On the Moon you would weigh 97.2 N, and a scale would read 9.91164 kg.
Try this example →60 kg on Jupiter
You get| Weight there (N) | 1,487.4 |
| A scale would read (kg) | 151.673 |
| Gravity compared with Earth (×) | 2.52788 |
| Weight on Earth (N) | 588.399 |
On Jupiter you would weigh 1,487.4 N, about 2.52788 times your Earth weight.

💡 Why is gravity different on each planet?
Surface gravity depends on a planet's mass and radius: g = GM ÷ r². The Moon has about 1/81 of Earth's mass, so even though it is smaller, its surface gravity is only about one-sixth of Earth's.
❓ Frequently asked questions
Does my mass change on the Moon?
No. Mass is the amount of matter in you and stays the same. Only your weight, the pull of gravity, changes.
How much less do you weigh on the Moon?
About one-sixth (16.5%) of your Earth weight, because the Moon's gravity is 1.62 m/s².
Where would I weigh the most?
Of the planets, on Jupiter, about 2.5 times your Earth weight.
What is the formula for weight?
Weight = mass × acceleration due to gravity, W = mg, measured in newtons.
