Flow Units: CFM -Cubic feet per minute.
ACFM -Actual cubic feet per minute (pressure and temperature condition must also be stated)
ICFM -Inlet cubic feet per minute based upon the inlet pressure and temperature at the cylinder flange.
SCFM -Standard cubic feet per minute is gas flow measured at standard conditions (14.7 psia & 60 °F).
MMSCFD -Million standard cubic feet per day is million cubic feet of gas per day measured at standard conditions (14.7 psia & 60 °F). (not to be confused with MSCFD, 1000 SCFD)
Sm
3
/hr -Standard cubic meters per hour, measured at standard metric conditions( 1 Atm & 15 °C). Used primarily in Canada, South America, and New Zealand
Nm
3
/hr -Normal cubic meters per hour, measured at normal metric conditions (1 Atm & 0 °C). Used primarily in Europe.
