FAQ

What is the conversion factor from L/min to gph (US)?
1 L/min equals 15.85032 gph (US). To convert, multiply the value in litres per minute by 15.85032.
How do I convert 1 L/min to gph (US)?
1 L/min = 15.8503 gph (US). For any value, multiply by 15.85032.
How do I convert gph (US) back to L/min?
Divide by the same factor — or equivalently, multiply by 0.0630902. So 1 gph (US) = 0.0630902 L/min.
When would I need to convert litre per minute to US gallon per hour?
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 gph (US) is a frequently needed conversion for flow datasheet preparation.
Is the conversion exact?
Yes. Both L/min and gph (US) are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
