Quick answer
Standard cubic meters per minute corrects actual flow for temperature and pressure so flows at different site conditions can be fairly compared.
SCMM = ACFM x 0.0283168 x (Pactual/Pstd) x (Tstd/Tactual)
How to use the Standard Cubic Meters Per Minute Calculator
- 1Enter the actual measured airflow in ACFM along with its temperature and pressure.
- 2Enter the reference standard temperature and pressure (commonly 68F/14.7 psia).
- 3The calculator applies the ideal gas correction and converts units to SCMM.

Frequently asked questions
Why not just use ACFM everywhere?
Actual flow varies with temperature and pressure at the measurement point, so standard conditions let you compare fairly across sites.
Is this the same idea as SCFM?
Yes — SCMM is simply the metric equivalent of standard cubic feet per minute (SCFM).
