What Is "SCFM"?

SCFM is an acronym for standard cubic feet per minute. It is the volumetric flow rate of a gas corrected to standardized conditions of temperature and pressure, which makes it equivalent to the mass flow rate of the gas.

Standard conditions vary, depending on who is defining them. As of 2014, there is no universally accepted set of standard or normalized conditions. In countries using the International System of Units, normal cubic meter is a term used to denote the volume of gas at some standard condition. Temperature standards have the greatest effect on standard cubic feet per minute because variations in temperature results in significant volume variations.
