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.

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