Weight on Other Planets Calculator
Find your weight on another planet or the Moon.
Your mass is fixed, but your weight changes with each world's gravity.
How the Math Works
Weight on other planets is calculated using the formula W = m × g(body), where weight (W) equals mass (m) multiplied by gravitational acceleration (g) of the celestial body. Your mass remains constant throughout the universe, but gravitational acceleration varies dramatically across planets - from 24.79 m/s² on Jupiter to 1.62 m/s² on our Moon. By inputting your Earth mass in kilograms and selecting a destination world, the calculator multiplies these values to reveal your weight in newtons or pounds on that specific body.
Practical Applications
To use this calculator practically, first determine your mass in kilograms (your bathroom scale reading divided by 2.2046). Select any solar system body - from Mercury's gentle 3.7 m/s² gravity to Saturn's massive 10.4 m/s² pull. Enter your mass and hit calculate to instantly see your weight in both metric and imperial units. This tool works for all planets, dwarf planets, and major moons, making space science accessible for classroom projects or sci-fi enthusiasts planning hypothetical interplanetary adventures.
Day-to-Day Use
While you can't take your new Martian weight to the doctor's office, this calculator offers surprising real-world value. It deepens our understanding of gravity's role in everyday experiences - why astronauts float in space and why you'd need a special scale on the Moon. Teachers use it to make physics engaging, while curious minds gain perspective on Earth's gravitational 'sweet spot.' The calculator also sparks important conversations about space exploration, showing future astronauts exactly how much equipment they can realistically transport to other worlds.
Worked example
70 kg on Mars (g = 3.71) → 259.7 N, like 26.5 kg on Earth.
FAQ
Where would I weigh the most?
On Jupiter, with surface gravity about 2.5 times Earth's.
