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.

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

total number of rooms = 5
