Your Weight on Other Planets Calculator
Use our weight on other planets calculator to see how your Earth weight (lb) changes on Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, the Moon, and Ganymede. Includes an easy formula and a quick weight on other planets chart.
Does Your Weight Change on Different Planets?
Yes. Your weight changes on different planets because weight depends on gravity. Your mass stays the same, but different worlds have different surface gravity, so the force pulling you down is different.
That’s why you’d weigh less on the Moon or Mars and much more on Jupiter (if you could stand on a solid surface at the same reference level).
This calculator takes your Earth weight in pounds (lb) and multiplies it by each world’s gravity factor relative to Earth to estimate your weight there.
Weight on Other Planets Formula
Convert Earth weight using a gravity multiplier for each planet or moon.
GravityFactor_world is surface gravity relative to Earth (Earth = 1.00).

Frequently Asked Questions
Because different planets and moons have different gravity. Weight depends on gravity, so the force pulling you down changes even though your mass stays the same.
Multiply your Earth weight by a gravity factor for the planet or moon: Weight_world = Weight_earth × GravityFactor_world.
If you enter kilograms, you are usually entering mass, not weight. This calculator uses Earth weight in pounds. If you want to start from mass, you would convert mass to weight using the local gravity.
Yes. The chart lists gravity factors relative to Earth, and the calculator uses those factors to estimate your weight on each world.
