About Converting Gallon per Minutes to Milliliter per Minutes
Gallon per Minutes and Milliliter 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 most often used for us residential and commercial plumbing fixture flow ratings.
Formula
milliliter per minutes = gallon per minutes × 3785.411784
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 milliliter per minutes equals 1.666667e-8 base units, so dividing one by the other gives the direct gallon per minutes-to-milliliter per minutes factor of 3785.411784.
Simple example
1 gal/min × 3785.411784 = 3,785.411784 mL/min
1 gallon per minutes = 3,785.411784 milliliter per minutes.
Real-world example
60 gal/min × 3785.411784 = 227,124.707 mL/min
60 gallon per minutes = 227,124.707 milliliter 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 milliliter per minutes?
Milliliter per Minutes (mL/min) is a unit of flow rate.
Is the gallon per minutes to milliliter per minutes conversion exact?
Yes. Both gallon per minutes and milliliter per minutes are defined by fixed standards rather than physical artifacts, so the factor of 3785.411784 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.
