Use this online Physics conversion CFM calculator to calculate the air flow of a pipe. It is calculated in either Cubic Feet per Minute (CFM) or Feet per Minute (FPM). This online calculator helps you to calculate either of the three parameters namely, the air flow in FPM (Feet per Minute), CFM and the area in square feet. By knowing any two parameters we can calculate the remaining parameter using this cubic feet per minute conversion calculator.
If the FPM and Area is equal to 5 and 25ft^2, then
CFM = 5 x 25
