Why does my weight change on other planets?

Weight is the force of gravity pulling on your mass (W = m × g). Each planet has a different surface gravity, so even though your mass is constant, the gravitational pull — and therefore your weight — changes from planet to planet.

What surface gravity values are used?

The tool uses standard mean surface gravity values in m/s²: Mercury 3.70, Venus 8.87, Earth 9.807, Moon 1.62, Mars 3.72, Jupiter 24.79, Saturn 10.44, Uranus 8.87, Neptune 11.15, Pluto 0.62.

Does this calculate weight on the surface or in orbit?

It calculates weight at the surface of each body. In orbit you would be in free fall, experiencing apparent weightlessness regardless of the planet's gravity.

Can I enter my weight in kilograms?

Yes. Use the unit toggle to switch between pounds (lb) and kilograms (kg). The results update instantly in the same unit you selected.

Why is Jupiter's gravity so much higher?

Jupiter is the most massive planet in the solar system — over 300 times Earth's mass — giving it a very strong gravitational field at its cloud-top "surface."

Is Pluto really a planet?

Pluto was reclassified as a dwarf planet by the IAU in 2006, but it is included here for reference because many people are curious about it.

Enter your Earth weight and see your weight on every planet, the Moon, and Pluto instantly.

Your Earth Weight

Your mass: — kg (constant everywhere)

Earth surface gravity = 9.807 m/s². Weight = mass × local gravity. Your mass never changes — only the gravitational pull does.

Summary

Enter your Earth weight and see your weight on every planet, the Moon, and Pluto instantly.

How it works

Enter your weight in the input field and select pounds or kilograms.
The tool divides your weight by Earth's surface gravity to find your mass.
For each planet, it multiplies your mass by that planet's surface gravity.
Results are displayed instantly as a visual card grid with a comparison bar.
Switch between lb and kg units at any time — values update immediately.
