Your weight on other planets
How much would you weigh on Mars, the Moon or Jupiter?
Your weight depends not on your mass alone but on the gravity of the body you stand on. Enter your weight on Earth and instantly see how much you would weigh on every planet, the Moon and even the Sun. Your mass stays the same everywhere — only the scale reads differently.

How is this calculated?
We multiply your Earth weight by the relative surface gravity of each body (Earth = 1). On Mars it is about 0.38 — so you would weigh roughly 38 % of your Earth weight. The values come from the NASA Planetary Fact Sheet.
Weight is not the same as mass
Mass is the amount of matter in your body and never changes. Weight is the force gravity exerts on that mass. That is why you feel feather-light on the Moon even though you carry exactly as much matter as on Earth.
Frequently asked questions
Where would I be heaviest?
On the Sun — its gravity is nearly 28 times Earth’s. Among the planets, Jupiter has the strongest surface gravity (about 2.5×).
Where would I be lightest?
On Pluto. Gravity there is only about 6 % of Earth’s — a 70 kg person would weigh roughly 4.4 kg.
Does my mass change in space?
No. Your mass stays constant. Only your weight — the force on the scale — changes with gravity.
Why is there a weight on gas planets at all?
Gas planets have no solid surface; the value refers to the cloud tops (1 bar pressure). You could not actually stand there.
Does this work for pounds or stone too?
Yes, the ratio is unit-independent. Whether kg, pounds or stone — just multiply by the gravity factor.
Would I really weigh just 1/6 on the Moon?
Almost. Lunar gravity is about 16.5 % of Earth’s — roughly one sixth.
