Question

Weight on planet Mars ​

Answer 1

Mars: 0.38

weight = mass x surface gravity

multiplying your weight on Earth by the number above will give you your weight on the surface of Mars

If you weigh 150 pounds (68 kg.) on Earth, you would weigh 57 lbs. (26 kg.) on Mars

Answer 2

You can 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. You can then calculate your weight on any other planet by using the surface gravity of that planet in the same equation.
