Your Weight on Other Planets

How do you calculate your weight on another planet?

Your weight is different on other planets because the gravity is different.

You have not changed of course, so your mass is the same.

We calculate weight by multiplying mass by the gravity on the surface of the planet.

Weight = Mass x Surface Gravity

So, if you know your weight on Earth and the surface gravity on Earth you can calculate your mass

Mass =	Weight on Earth
	Surface Gravity on Earth

Then you can work out your weight on any other planet by using the surface gravity of that planet using in first formula.

You can work it out for yourself using the values of the surface gravity of all the planets in the Solar System section of the Astronomy Section. You can then check your answers here.
