Cubic feet per minute (CFPM or CFM) is a non-SI unit of measurement of the flow of a gas or liquid that indicates how much volume in cubic feet pass by a stationary point in one minute. The higher the CFPM the better the suction. To convert cubic feet per minute to cubic meters per hour, multiply by 1.699.
Conversion factor for SI conversions
In order to perform these conversions the following information is required:
- 1 m=100 cm, 1 foot=0.3048 meter, 1 mL=1 cm3, 1 L=1,000 mL
- 1 cfm is another way of saying 1 ft³/min. Therefore,
giving us 1 cfm = 4.71945×10−4 m3 s−1
Also,
This comes out to be 1CFM = 0.47195 L s−1
CFPM, SCFM and ACFM
Standard cubic feet per minute (SCFM) corresponds to the CFPM in standard conditions, while actual cubic foot per minute (ACFM) explicitly corresponds to the CFPM in the actual conditions of operation.
Applications
The CFPM unit, along with its SI counterparts, is used with:
- Air compressor and pneumatic tool
- Computer cooling, specifically overclocking
- Fog machine
- Hydrology
- Industrial hygiene
- Ventilation engineering and HVAC
The CFPM unit was also formerly used in the engineering of carburetors, and is still used in fields where carburetors are still in service, such as the classic car and vintage aircraft hobbies.
