About Converting Gallon per Hours to Milliliter per Hours
Gallon per Hours and Milliliter 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
milliliter per hours = gallon per hours × 3785.411784
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 milliliter per hours equals 2.777778e-10 base units, so dividing one by the other gives the direct gallon per hours-to-milliliter per hours factor of 3785.411784.
Simple example
1 gal/h × 3785.411784 = 3,785.411784 mL/h
1 gallon per hours = 3,785.411784 milliliter per hours.
Real-world example
60 gal/h × 3785.411784 = 227,124.707 mL/h
60 gallon per hours = 227,124.707 milliliter per hours.

Frequently asked questions
How many milliliter per hours are in 1 gallon per hours?
1 gallon per hours equals 3,785.411784 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to milliliter per hours?
Multiply the gallon per hours value by 3785.411784. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to gallon per hours?
Use the reverse factor: 1 milliliter per hours equals 0.0002641721 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 milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
Is the gallon per hours to milliliter per hours conversion exact?
Yes. Both gallon per hours and milliliter per hours 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.
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.
