Weight on other planets calculator
Type what a scale shows on Earth, in kilograms or pounds, and see what the same scale would show on every planet.
That's about the same as an adult. There, a jump that clears 50 cm on Earth would clear about 1.322 m.
What it means
How heavy would that feel?
Uses each body’s mean surface gravity. The gas giants have no surface, so their figure is for the cloud tops; works the same in pounds.

Three things worth knowing
-
Moon ÷ 6, Mars × 0.38
On the Moon divide by six, on Mars multiply by 0.38, on Jupiter by 2.5. Venus and Uranus are almost like home, at 0.9.
-
Why gravity differs
Surface gravity grows with a world’s mass and shrinks with the square of its radius. Saturn is 95 times heavier than Earth but so wide that its pull at the clouds is only 6 % stronger.
-
Weight is not mass
An astronaut does not lose mass on the Moon. A 70 kg person still has 70 kg of inertia: just as hard to stop, but only a sixth as hard to lift.

Background
Why weight changes from world to world
A scale does not measure how much of you there is; it measures how hard gravity pulls you down. That pull depends on the world you stand on. The Moon’s gravity is about a sixth of Earth’s, so a 70 kg reading becomes 11.6 kg; Mars pulls with 38 %, Jupiter with 2.5 times Earth’s.
Your mass, the amount of matter, is the same everywhere. Only the weight, the force, changes.
