What would I weigh on another planet?

Every planet has a different gravitational force due to its mass. It is due to this gravitational force that every object in the universe with mass is attracted to every other object with mass. The measurement this force has on the human body can be measured with a scale. The greater the body of mass, the greater the gravitational pull between the object and the planet and thus the greater the measured weight of the body. This goes for the planet as well, the planet's gravitational force increases with its mass. Additionally, the gravitational pull is strongest at the center of the planet. The farther an object is from the planet's center, the weaker the gravitational pull. For this reason, a person's weight is not directly proportionate to the mass of a planet. The planet's radius must also be taken into account. For instance, just because Jupiter is 318 times as massive as Earth does not mean a person will weigh 318 times more on Jupiter. Since Jupiter's radius is greater that Earth's radius, it reduces the gravitational pull. This can be proven by the equation for gravitational force:

Force = (Object Mass x Planet's Mass)/Planet's Radius^2.
