Explanation

This page answers the cfm-to-liters-per-minute question directly: multiply cfm by 28.316846592 because 1 cubic foot per minute equals exactly 28.316846592 liters per minute.

That makes it useful for HVAC airflow, fans, ventilation, compressed-air specs, and equipment sheets where one source gives cfm and another expects L/min. It also covers shorthand searches such as cfm to l/min, cfm l/min, cfm to liters per minute, cfm to lpm, and practical values like 25 cfm to L/min or 1 cfm to L/min. This page is for cfm to L/min, not for L/s or SCFM conversions.
