The planet weight calculator shows what you'd weigh on other planets and the Moon! A fun way to learn about gravity and planetary differences.
Enter your Earth weight and select a planet (1=Mars, 2=Jupiter, 3=Moon). The calculator shows your weight there, gravity factor, and how high you could jump!
Your mass stays the same everywhere, but weight depends on gravity. On the Moon you'd weigh about 1/6 your Earth weight—on Jupiter, over twice as much!

Frequently Asked Questions
Weight is mass × gravity; different planets have different gravity.
No, mass is constant; only weight (gravitational force) changes.
In theory yes, but in a spacesuit you'd be limited!
Mercury: 0.38, Venus: 0.91, Saturn: 0.93, Uranus: 0.89, Neptune: 1.12.
Jupiter is massive with strong gravity, over twice Earth's!
