Enter the total cubic feet per minute (cfm) and the total number of rooms into the Calculator. The calculator will evaluate the Cfm Per Room.

## Cfm Per Room Formula

CFMR = CFM / R

Variables:

- CFMR is the Cfm Per Room (cfm/room)
- CFM is the total cubic feet per minute (cfm)
- R is the total number of rooms

To calculate Cfm Per Room, divide the cubic feet per minute by the number of rooms.

## How to Calculate Cfm Per Room?

The following steps outline how to calculate the Cfm Per Room.

- First, determine the total cubic feet per minute (cfm).
- Next, determine the total number of rooms.
- Next, gather the formula from above = CFMR = CFM / R.
- Finally, calculate the Cfm Per Room.
- 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) = 7450

total number of rooms = 5
