Cubic feet per minute

Cubic feet per minute

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.

Conversion factor for SI conversions

In order to find this conversion the following information is required:1m=100cm, 1foot=.3048meters, 1mL=1cm3, 1L=1000mL

1CFM is another way of saying frac{(1foot)^3}{minute}The conversion is as follows:frac{(1foot)^3}{minute}*frac{(.3048m)^3}{foot^3}*frac{(100cm)^3}{(1m)^3}*frac{1mL}{(1cm)^3}*frac{1L}{1000mL}*frac{1minute}{60sec}

This comes out to be 1CFM = .47195L/s

CFPM, SCFM and ACFM

SCFM (Standard cubic feet per minute) corresponds to the CFPM in Standard conditions, while ACFM (actual cubic feet per minute) explicitly corresponds to the CFPM in the actual conditions of operation.

Applications

The CFPM unit, along with its SI counterparts, is used with:
* Air compressors and pneumatic tools
* Computer cooling, specifically overclocking
* Fog machines
* 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.
