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.


  1. First, determine the weight on earth (lb). 
  2. Next, determine the mass ratio of the planet to earth. 
  3. Next, gather the formula from above = PW = EW * MR.
  4. Finally, calculate the Planet Weight.
  5. 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 = ?
