About Converting Gallon per Minutes to Liter per Minutes
Gallon per Minutes and Liter 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. Gallon per Minutes is typically associated with united States (plumbing, pump, and irrigation industry standard), while Liter per Minutes is typically associated with common household and light-industrial flow specification worldwide.
Formula
liter per minutes = gallon per minutes × 3.785411784
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 minutes equals 0.0000166666666667 base units, so dividing one by the other gives the direct gallon per minutes-to-liter per minutes factor of 3.785411784.
Simple example
1 gal/min × 3.785411784 = 3.785411784 L/min
1 gallon per minutes = 3.785411784 liter per minutes.
Real-world example
60 gal/min × 3.785411784 = 227.124707 L/min
60 gallon per minutes = 227.124707 liter per minutes.

What is a 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.
What is a liter per minutes?
Liter per Minutes (L/min) measures volumetric flow rate. One liter of volume passing a point every minute. It is classified as a metric derived flow-rate unit.
Is the gallon per minutes to liter per minutes conversion exact?
Yes. Both gallon per minutes and liter per minutes are defined by fixed standards rather than physical artifacts, so the factor of 3.785411784 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
