Weight on the Moon
Your weight is your mass times local gravity - and lunar gravity is one-sixth of Earth's. Enter your Earth weight and see your Moon weight instantly, plus Mars, Jupiter and the rest of the solar system, because the scale reading is a local opinion.
Important distinction for science class: your mass never changes anywhere in the universe; weight is just the force your mass experiences under local gravity. On the Moon you would weigh 16% of Earth - but you would still be exactly you.

How to use
- Enter your weight on Earth (kg or lb - the ratio works the same in any unit).
- Read your weight on the Moon, Mars, Jupiter and the other planets.
- Note Jupiter: heavier gravity means the same you weighs 2.5 times more there.
Frequently asked questions
How much would I weigh on the Moon?
Multiply your Earth weight by 0.165 (lunar gravity is 1.62 m/s2 versus Earth's 9.81). A 60 kg person weighs about 9.9 kg-force on the Moon - light enough to jump over a car, in theory.
Why is weight different but mass the same?
Mass is the amount of matter in you - constant everywhere. Weight is mass times local gravitational acceleration, so it changes with location while you stay the same size.
Where would I weigh the most in the solar system?
Jupiter: its gravity is 2.53 times Earth's, so a 70 kg person weighs 177 kg there. You could not stand, breathe or survive - but the scale reading would be impressive.
Is this calculation scientifically accurate?
The gravity ratios are the standard values used in physics education. Real weight also varies slightly with altitude and latitude even on Earth, by about 0.5% - far less than the planetary differences shown here.
