Formula
gph (US) = L/s × 951.0194
Multiply any value in litres per second by 951.0194 to obtain the value in US gallons per hour.
Worked example
Convert 1 L/s to gph (US).
- 01Start with 1 L/s.
- 02Multiply by the conversion factor: 1 × 951.0194 = 951.019 gph (US).
Result1 L/s = 951.019 gph (US)

FAQ
What is the conversion factor from L/s to gph (US)?
1 L/s equals 951.0194 gph (US). To convert, multiply the value in litres per second by 951.0194.
How do I convert 1 L/s to gph (US)?
1 L/s = 951.019 gph (US). For any value, multiply by 951.0194.
How do I convert gph (US) back to L/s?
Divide by the same factor — or equivalently, multiply by 0.001051503. So 1 gph (US) = 0.0010515 L/s.
When would I need to convert litre per second 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/s to gph (US) is a frequently needed conversion for hydraulic sizing.
Is the conversion exact?
Yes. Both L/s and gph (US) are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
