Enter the total feet per second (FPS) and the mass (grams) into the Calculator. The calculator will evaluate the Joules from FPS. 

Joules from FPS Formula

J = (FPS/3.2808399)^2 * .5 * m/1000

Variables:

  • J is the Joules from FPS (joules)
  • FPS is the total feet per second (FPS)
  • m is the mass (grams)

How to Calculate Joules from FPS?

The following steps outline how to calculate the Joules from FPS.


  1. First, determine the total feet per second (FPS). 
  2. Next, determine the mass (grams). 
  3. Next, gather the formula from above = J = (FPS/3.2808399)^2 * .5 * m/1000.
  4. Finally, calculate the Joules from FPS.
  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.

total feet per second (FPS) = 4000

mass (grams) = 30
