About Converting Gallon per Minutes to Liter per Seconds
Gallon per Minutes and Liter per Seconds 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. Gallon per Minutes is typically associated with united States (plumbing, pump, and irrigation industry standard), while Liter per Seconds is typically associated with common in municipal water-utility and industrial flow specifications internationally.
Formula
liter per seconds = gallon per minutes × 0.0630901964
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct gallon per minutes-to-liter per seconds factor of 0.0630901964.
Simple example
1 gal/min × 0.0630901964 = 0.0630901964 L/s
1 gallon per minutes = 0.0630901964 liter per seconds.
Real-world example
60 gal/min × 0.0630901964 = 3.785411784 L/s
60 gallon per minutes = 3.785411784 liter per seconds.

Gallon per Minutes vs. Liter per Seconds
| Aspect | Gallon per Minutes | Liter per Seconds |
|---|---|---|
| Family | US customary flow-rate unit | metric derived flow-rate unit |
| Typical use | US residential and commercial plumbing fixture flow ratings | Municipal water supply and treatment plant flow rates |
| Where it's used | United States (plumbing, pump, and irrigation industry standard) | Common in municipal water-utility and industrial flow specifications internationally |
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
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
