About Converting Liter per Minutes to Gallon per Minutes
Liter per Minutes 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 Minutes is typically associated with common household and light-industrial flow specification worldwide, while Gallon per Minutes is typically associated with united States (plumbing, pump, and irrigation industry standard).
Formula
gallon per minutes = liter per minutes × 0.264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per minutes equals 0.0000166666666667 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct liter per minutes-to-gallon per minutes factor of 0.264172052358.
Simple example
1 L/min × 0.2641720524 = 0.2641720524 gal/min
1 liter per minutes = 0.2641720524 gallon per minutes.
Real-world example
60 L/min × 0.2641720524 = 15.85032314 gal/min
60 liter per minutes = 15.85032314 gallon per minutes.

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.
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.
Is the liter per minutes to gallon per minutes conversion exact?

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.
