Enter the total cubic feet per minute (CFM) and the cross-sectional area (ft^2) into the FPS from CFM Calculator. The calculator will evaluate the FPS from CFM.

## FPS from CFM Formula

The following two example problems outline the steps and information needed to calculate the FPS from CFM.

FPS = CFM / A /60

Variables:

- FPS is the FPS from CFM (ft/s)
- CFM is the total cubic feet per minute (CFM)
- A is the cross-sectional area (ft^2)

To calculate FPS from CFM, divide the CFM by the cross-sectional area, then divide again by 60.

## How to Calculate FPS from CFM?

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

- First, determine the total cubic feet per minute (CFM).
- Next, determine the cross-sectional area (ft^2).
- Next, gather the formula from above = FPS = CFM / A /60.
- Finally, calculate the FPS from CFM.
- 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 cubic feet per minute (CFM) = 250

cross-sectional area (ft^2) = 15

FPS = CFM / A /60** **= ?
