The Ultimate Guide to Converting Inches of Water Gauge (IWG) to Cubic Feet per Minute (CFM) in HVAC Systems

When working with HVAC systems, it is important to be able to compare IWG to CFM to ensure that the system is operating efficiently. IWG stands for inches of water gauge, and it is a measure of the pressure of the air in the system. CFM stands for cubic feet per minute, and it is a measure of the volume of air that is flowing through the system.

In order to compare IWG to CFM, you will need to use a conversion factor. The conversion factor is 1 IWG = 0.00231 CFM. This means that for every 1 inch of water gauge, there is 0.00231 cubic feet of air flowing through the system.
