About Converting Liter per Seconds to Imperial gallon per Hours
Liter per Seconds and Imperial gallon per Hours both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Liter per Seconds is most often used for municipal water supply and treatment plant flow rates.
Formula
imperial gallon per hours = liter per seconds × 791.889293877
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per seconds equals 0.001 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct liter per seconds-to-imperial gallon per hours factor of 791.889293877.
Simple example
1 L/s × 791.8892939 = 791.8892939 imp gal/h
1 liter per seconds = 791.8892939 imperial gallon per hours.
Real-world example
60 L/s × 791.8892939 = 47,513.35763 imp gal/h
60 liter per seconds = 47,513.35763 imperial gallon per hours.

Understanding the Liter per Seconds
Liter per Seconds (L/s) measures volumetric flow rate. One liter of volume passing a point every second — used for larger flows than liter-per-minute conveniently describes. It is classified as a metric derived flow-rate unit.
Where it's used: Common in municipal water-utility and industrial flow specifications internationally
L/s vs. L/min. Both measure the same quantity at different time scales; 1 L/s equals 60 L/min. L/s is typically used for larger, continuous industrial or utility flows, while L/min suits smaller household-scale flows.
Uses of the Liter per Seconds today
- Municipal water supply and treatment plant flow rates
- Industrial process flow specifications
- Stream and river discharge measurement at moderate scales
