Step 1
Select a planet. Selecting a planet will fill in the mass and radius fields. If you would like to use another object, do not select anything from the menu and simply enter the mass in kilograms and the radius in meters. Keep in mind that selecting a planet simply puts numbers in the mass and radius fields, you can still change them to any values you like.
Mass: (kg)
Radius: (m)
Step 2
Now enter your weight on earth. It can be in pounds, kilograms, or anything else. The units used here will be the same as the units of the output, so if you use pounds your answer will also be in pounds.
Weight on Earth:
Results
Your weight below is in the same units that you entered it in. The force of the planet's gravity is also displayed, both in m/s/s and as a multiple of the strength of earth's surface gravity (also known as a "g"). Escape velocity in m/s is also included. Bear in mind that acceleration due to gravity, strength of gravity relative to the earth, and escape velocity all depend only on the mass and radius of the planet. Only weight depends on the mass of the observer.
Your new weight:
Acceleration due to gravity: (m/s/s)
Strengh relative to Earth: (Earth = 1)
Escape velocity*: (m/s)
* The speed of light is 2.9979 x 10^8 m/s, if the escape velocity is higher than this, the object is a black hole.
