unity. Table 1 gives the numerical values for 29.92/P. To find acfm, multiply the scfm by the value found in the table opposite the vacuum pressure (P). A direct ratio for converting scfm to acfm (sL/s to aL/s) for various pressures is given in table 2. Multiply the scfm (sL/s...
How do I convert to SCFM? We can easily derive the conversion equation from the ideal gas law and the mass flow rate equation above. The mass flow rate is equal whether the flow is stated in CFM or SCFM. m/t = ρactual*CFM = ρstd*SCFM → SCFM = CFM *(ρactual/ ρstd) = CFM...
SCFM and ACFM both have units of volume per unit time. Ordinarily in physics, volumes are measured in cubic meters (m3) or some variation thereof, such as cubic centimeters (cm3, equivalent to milliliters or mL) and time is in seconds. In this case, both the volume (ft3) and time (...

CFM (M3/min.) is often stated when someone may actually be looking for SCFM, which is Standard Cubic Feet per Minute. This can also be a confusing unit, as the unit revolves around a reference point in order to be able to adapt it to your point of use conditions. We use a “Standa...

In specifying blower performance, major problems occur in distinguishing ACFM from SCFM, and in correctly converting from one to the other. Some people even use SCFM and ACFM interchangeably. SCFM is normally used to designate flow in terms of some base or reference pressure, temperature and rel...
Inlet Cubic Feet per Minute - ICFM - is used by compressor vendors to establish conditions in front of additional equipment like inlet filter, blower or booster. When air passes through the filter there will be a pressure drop. The conversion from ACFM to ICFM can be expressed as ICFM =...
SCFM = ACFM × (294.26 / (Temperature + 273.15)) × ((14.7 + Pressure) / 14.7) How can I account for humidity when converting ACFM to SCFM? To account for humidity, you may need to adjust the conversion formula to include the specific humidity or moisture content of the air. This ...
