Cubic feet per minute (CFM) is a measure used in Industrial hygiene and ventilation engineering. It describes the rate of flow of a gas or air volume into or out of a space.

A standard measurement of airflow that indicates how many cubic feet of air pass by a stationary point in one minute. The higher the number, the more air is being forced through the system. The volumetric flow rate of a liquid or gas in cubic feet per minute. 1 CFM equals approximately 0.47 liter per second.
