What Are CFM and SCFM? Volumetric air flow is measured in cubic feet per minute, but because the density of air and other gases changes with temperature and pressure, this number varies. Density varies directly with pressure and inversely with temperature. Engineers often refer to CFM as Actual...
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...
The distinction between SCFM and CFM is important because air density will change with pressure and temperature. This can be seen from taking a look at the ideal gas law. As you may remember, density = mass/volume. When the ideal gas law is rearranged, the air density can be seen to ...

CFM为：立方英尺/分 SCFM为：立方英尺/分； S是标准的意思，所谓的“标准”就是指在标准的温度和压强下。以下是国外网站上的解释：SCFM is the amount (volume) of air that would happen if your air were at room temperature, and atmospheric pressure (0ft above sea level, 14.7psi).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 ...
For Case 1, if we had merely plugged in 25CFM into the above equation, we would have been undersized by a factor of about three. For Case 2, if we would have used 200CFM, we would have been under by 2% if we had not converted to SCFM. ...
