- LB/HR to SCFM Calculator
- SLPM to SCFH Calculator
- Cfm Per Room Calculator

## CFH Formula

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

CFH = V/T * 60

Variables:

- CFH is the CFH (ft^3/hr)
- V is the total volume of flow (ft^3)
- T is the total time (min)

To calculate the CFH, divide the total volume of flow by the total time.

## How to Calculate CFH?

The following steps outline how to calculate the CFH.

- First, determine the total volume of flow (ft^3).
- Next, determine the total time (min).
- Next, gather the formula from above = CFH = V/T * 60.
- Finally, calculate the CFH.
- 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 volume of flow (ft^3) = 125

total time (min) = 55

CFH = V/T * 60** **= ?
