WebAug 15, 2016 · SCFM (Standard Cubic Feet per Minute) measures air output, like ACFM, but uses a standard that takes atmospheric conditions into account. SCFM is a set of specific parameters determined by the American Society of Mechanical Engineers (ASME) that are recognized across many industries. These SCFM calculations are based on … WebOct 23, 2010 · FPm is 4005 times the square root of the pressure. So to convert 1 " w.c. to fpm its the square root of 1, which is 1 times 4005, which is 4005 fpm. Then you multiply the fpm by the area of the space the air is moving through. So if you have 1 " wc moving through a hole that's 1 square foot in area, that's 4005 cubic feet per minute.
