About Converting Gallon per Hours to Megaliter per Hours
Gallon per Hours 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. Both are volumetric flow rate units.
Formula
megaliter per hours = gallon per hours × 0.000003785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 megaliter per hours equals 0.277777777778 base units, so dividing one by the other gives the direct gallon per hours-to-megaliter per hours factor of 0.000003785411784.
Simple example
1 gal/h × 0.000003785411784 = 0.0000037854 ML/h
1 gallon per hours = 0.0000037854 megaliter per hours.
Real-world example
60 gal/h × 0.000003785411784 = 0.0002271247 ML/h
60 gallon per hours = 0.0002271247 megaliter per hours.

How do I convert megaliter per hours back to gallon per hours?
Use the reverse factor: 1 megaliter per hours equals 264,172.0524 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a megaliter per hours?
Megaliter per Hours (ML/h) is a unit of flow rate.
Is the gallon per hours to megaliter per hours conversion exact?
Yes. Both gallon per hours and megaliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.000003785411784 used above is exact to as many digits as you choose to display.
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.
