About Converting Imperial gallon per Hours to Cubic Millimeter per Minutes
Imperial gallon per Hours and Cubic Millimeter 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. Both are volumetric flow rate units.
Formula
cubic millimeter per minutes = imperial gallon per hours × 75768.1666667
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 cubic millimeter per minutes equals 1.666667e-11 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cubic millimeter per minutes factor of 75768.1666667.
Simple example
1 imp gal/h × 75768.16667 = 75,768.16667 mm3/min
1 imperial gallon per hours = 75,768.16667 cubic millimeter per minutes.
Real-world example
60 imp gal/h × 75768.16667 = 4,546,090 mm3/min
60 imperial gallon per hours = 4,546,090 cubic millimeter per minutes.

Multiply the imperial gallon per hours value by 75768.16667. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per minutes back to imperial gallon per hours?
Use the reverse factor: 1 cubic millimeter per minutes equals 0.0000131982 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a cubic millimeter per minutes?
Cubic Millimeter per Minutes (mm3/min) is a unit of flow rate.
Is the imperial gallon per hours to cubic millimeter per minutes conversion exact?
Yes. Both imperial gallon per hours and cubic millimeter per minutes are defined by fixed standards rather than physical artifacts, so the factor of 75768.16667 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.
