About Converting Liter per Seconds to Gallon per Minutes
Liter per Seconds and Gallon per Minutes 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 typically associated with common in municipal water-utility and industrial flow specifications internationally, while Gallon per Minutes is typically associated with united States (plumbing, pump, and irrigation industry standard).
Formula
gallon per minutes = liter per seconds × 15.8503231415
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 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct liter per seconds-to-gallon per minutes factor of 15.8503231415.
Simple example
1 L/s × 15.85032314 = 15.85032314 gal/min
1 liter per seconds = 15.85032314 gallon per minutes.
Real-world example
60 L/s × 15.85032314 = 951.0193885 gal/min
60 liter per seconds = 951.0193885 gallon per minutes.

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
Understanding the Gallon per Minutes
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Where it's used: United States (plumbing, pump, and irrigation industry standard)
Uses of the Gallon per Minutes today
- US residential and commercial plumbing fixture flow ratings
- US pump and irrigation system specifications
- US pool and spa filtration system sizing
