The Gravity Weight Converter (also called a planet weight calculator or weight on other planets calculator) shows how much you would weigh on the Moon, Mars, Jupiter, and every major planet and moon. Enter your weight on Earth and get your weight on other planets instantly. Gravity on different planets varies a lot—your weight on the Moon is about one-sixth of your Earth weight, while your weight on Jupiter would be more than double.
Whether you're curious about your weight on the Moon, weight on Mars, or weight on Jupiter, this gravity calculator uses standard surface gravity ratios for each body. Your mass stays the same everywhere; only the pull of gravity changes. So you'd feel light on the Moon and heavy on Jupiter. Perfect for students, space fans, or anyone who's ever wondered 'how much would I weigh on Mars?'
The calculator supports both pounds and kilograms. It's free, works on any device, and shows your weight on the Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and our Moon in one clear table. Try it and see how gravity on different planets changes your weight!

Our calculator uses proven formulas and up-to-date data to give you accurate results. Here's a transparent look at the methodology behind your calculation.
The Formula
Weight on planet = Your weight on Earth × (Planet's surface gravity / Earth's gravity)Each body has a fixed ratio (e.g. Moon 0.17, Mars 0.38, Jupiter 2.34)Example: 150 lbs on Earth × 0.17 = 25.5 lbs on the MoonExample: 70 kg on Earth × 2.34 ≈ 164 kg on JupiterWe multiply your Earth weight by the surface gravity ratio of each planet or moon. Ratios are relative to Earth = 1.0. Your mass is unchanged; only the gravitational pull (and thus your weight) changes. Results are shown in the same unit you entered (lbs or kg).
Enter your weight on Earth and choose pounds or kilograms. This is the weight a scale would show you on Earth.
We multiply your weight by the surface gravity of the Moon, Mars, Jupiter, and each other body (e.g. Moon 0.17, Mars 0.38, Jupiter 2.34).
The calculator shows your weight on the Moon, Mars, Jupiter, and all listed bodies, plus where you'd weigh the least and most.
