Standard Cubic Feet Per Minute. At “standard conditions” (see above) will one standard cubic foot of air actually occupy one cubic foot of volume. Another way to express one standard cubic foot of air is .075 of a pound of air. A standard cubic foot varies in volume as it deviates from standard conditions, but it always weighs .075 of a pound. Therefore, SCFM is a measure of weight, regardless of volume. (see corrections for altitude chart).
