About Converting Cubic Millimeters per Millisecond to Imperial gallon per Hours
Cubic Millimeter per Millisecond and Imperial gallon 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
imperial gallon per hours = cubic millimeters per millisecond × 0.791889293877
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per millisecond equals 0.000001 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic millimeter per millisecond-to-imperial gallon per hours factor of 0.791889293877.
Simple example
1 mm3/ms × 0.7918892939 = 0.7918892939 imp gal/h
1 cubic millimeter per millisecond = 0.7918892939 imperial gallon per hours.
Real-world example
60 mm3/ms × 0.7918892939 = 47.51335763 imp gal/h
60 cubic millimeters per millisecond = 47.51335763 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 cubic millimeter per millisecond?
1 cubic millimeter per millisecond equals 0.7918892939 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per millisecond to imperial gallon per hours?
Multiply the cubic millimeter per millisecond value by 0.7918892939. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to cubic millimeter per millisecond?
Use the reverse factor: 1 imperial gallon per hours equals 1.262802778 cubic millimeters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the cubic millimeter per millisecond to imperial gallon per hours conversion exact?
Yes. Both cubic millimeter per millisecond and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.7918892939 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.
