Step onto another world and the bathroom scale would read something completely different — not because you changed, but because gravity did. This weight on other planets calculator takes your Earth weight and shows what you would weigh on the Moon, Mars, Jupiter and every other body in the solar system, using each one's real surface gravity.
Why your weight changes but your mass does not
There is an important difference between mass and weight. Your mass — the amount of matter in your body — never changes, no matter where you go. Your weight is the force gravity exerts on that mass, so it depends entirely on where you are standing. On a low-gravity world you feel featherlight; on a high-gravity world you feel crushingly heavy, even though you are the same person.
How the calculation works
Every result here is your weight multiplied by that body's surface gravity relative to Earth (Earth = 1.00). A few reference values: the Moon is about 0.166, Mars 0.377, Jupiter 2.36, and the Sun a staggering 27.9. So a 70 kg person "weighs" about 12 kg on the Moon, 26 kg on Mars, 165 kg at Jupiter's cloud tops, and nearly two tonnes on the Sun's surface.
Where would you weigh the most and least?
Among the planets, Jupiter makes you the heaviest at roughly 2.36× your Earth weight, while Pluto makes you the lightest at about 0.06×. The Moon sits near the bottom at one sixth of Earth. The Sun is in a league of its own — you could never actually stand on it, but its gravity would multiply your weight nearly 28 times.
Try it yourself
Enter your weight in kilograms or pounds and the grid updates instantly for all ten bodies. It is a fun, tangible way to understand gravity — great for students, space fans, and anyone curious about what a trip across the solar system would feel like.
Surface-gravity ratios are based on NASA's planetary fact sheet. "Weight" on the gas giants and the Sun refers to the cloud-top or photosphere level, where you could not physically stand.
