FAQ

What is the conversion factor from L/min to cfm?
1 L/min equals 0.03531467 cfm. To convert, multiply the value in litres per minute by 0.03531467.
How do I convert 1 L/min to cfm?
1 L/min = 0.0353147 cfm. For any value, multiply by 0.03531467.
How do I convert cfm back to L/min?
Divide by the same factor — or equivalently, multiply by 28.31685. So 1 cfm = 28.3168 L/min.
When would I need to convert litre per minute to cubic foot 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. L/min to cfm is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both L/min and cfm are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
