In Europe, the standard temperature is most commonly defined as 0 °C, but not always. In the United States, the EPA defines standard conditions for volume and volumetric flow as a temperature of 293 K (68 °F) and a pressure of 101.3 kilopascals (29.92 in. Hg), [1] although various industry users may use definitions from 60 °F to 78 °F.
Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.

An actual volume can be converted to a standard volume using the following equation: [6] [7] V s = V a × F p × F t × (F pv) 2. Where, V s: standard volume V a: actual volume (sometimes shown as V r for registered volume) F p: pressure factor (sometimes shown as P m for pressure multiplier)

The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .

This standard is also called normal temperature and pressure (abbreviated as NTP). However, a common temperature and pressure in use by NIST for thermodynamic experiments is 298.15 K (25 °C, 77 °F) and 1 bar (14.5038 psi, 100 kPa).
