About Converting Gallon per Minutes to Megaliter per Hours
Gallon per Minutes and Megaliter per Hours 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
megaliter per hours = gallon per minutes × 0.00022712470704
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 megaliter per hours equals 0.277777777778 base units, so dividing one by the other gives the direct gallon per minutes-to-megaliter per hours factor of 0.00022712470704.
Simple example
1 gal/min × 0.000227124707 = 0.0002271247 ML/h
1 gallon per minutes = 0.0002271247 megaliter per hours.
Real-world example
60 gal/min × 0.000227124707 = 0.0136274824 ML/h
60 gallon per minutes = 0.0136274824 megaliter per hours.

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 megaliter per hours?
Megaliter per Hours (ML/h) is a unit of flow rate.
Is the gallon per minutes to megaliter per hours conversion exact?
Yes. Both gallon per minutes and megaliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.000227124707 used above is exact to as many digits as you choose to display.

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.
