FAQ

What is the conversion factor from cfm to L/min?
1 cfm equals 28.31685 L/min. To convert, multiply the value in cubic feet per minute by 28.31685.
How do I convert 1 cfm to L/min?
1 cfm = 28.3168 L/min. For any value, multiply by 28.31685.
How do I convert L/min back to cfm?
Divide by the same factor — or equivalently, multiply by 0.03531467. So 1 L/min = 0.0353147 cfm.
When would I need to convert cubic foot per minute to litre per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. cfm to L/min is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both cfm and L/min are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
