Enter the weight on earth (lb) and the mass ratio of the planet to earth into the Planet Weight Calculator. The calculator will evaluate the Planet Weight.

## Planet Weight Formula

The following two example problems outline the steps and information needed to calculate the Planet Weight.

PW = EW * MR

Variables:

- PW is the Planet Weight (lb)
- EW is the weight on earth (lb)
- MR is the mass ratio of the planet to earth

To calculate the planet weight, multiply the weight on earth by the mass ratio of the planet to earth.

## How to Calculate Planet Weight?

The following steps outline how to calculate the Planet Weight.

- First, determine the weight on earth (lb).
- Next, determine the mass ratio of the planet to earth.
- Next, gather the formula from above = PW = EW * MR.
- Finally, calculate the Planet Weight.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

weight on earth (lb) = 150

mass ratio of the planet to earth = 2.5

PW = EW * MR** **= ?
