Find out how much you would weigh on other worlds in our solar system
Description
The Weight on Planets Calculator is a fun and educational science tool that demonstrates the power of surface gravity. While your “mass” (the amount of matter in your body) stays the same everywhere in the universe, your “weight” is a measure of the gravitational pull exerted on you by a planet. This tool takes your Earth Weight and applies the gravity factors of all the planets in our solar system (plus the Moon and Pluto) to show you how “heavy” or “light” you would feel elsewhere.
Inputs
- Weight (lbs or kg): Your weight as measured on Earth.
- Select Planet: Choose from Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, or the Moon.
Outputs
- Result: Your weight on the selected world (in the same units you provided).
Chart
- N/A: This tool provides a direct numeric gravity result.
“Good to Know”
- Gravity Kings: Jupiter is the heavyweight champion of our solar system. You would weigh more than twice as much there as you do on Earth!
- Floating on Pluto: On the dwarf planet Pluto, a 150 lb person would weigh only 9 lbs. You could jump incredibly high!
- The Magic of Venus: Venus is often called Earth’s twin because its surface gravity is almost the same (91% of Earth’s).
- Moon Jump: The Moon’s gravity is about 1/6th of Earth’s, which is why astronauts can hop around so easily in lunar footage.
