About Converting Cubic Millimeter per Seconds to Imperial gallon per Hours
Cubic Millimeter per Seconds 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 millimeter per seconds × 0.000791889293877
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per seconds equals 1e-9 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 seconds-to-imperial gallon per hours factor of 0.000791889293877.
Simple example
1 mm3/s × 0.0007918892939 = 0.0007918893 imp gal/h
1 cubic millimeter per seconds = 0.0007918893 imperial gallon per hours.
Real-world example
60 mm3/s × 0.0007918892939 = 0.0475133576 imp gal/h
60 cubic millimeter per seconds = 0.0475133576 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 cubic millimeter per seconds?
1 cubic millimeter per seconds equals 0.0007918893 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per seconds to imperial gallon per hours?
Multiply the cubic millimeter per seconds value by 0.0007918892939. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to cubic millimeter per seconds?
Use the reverse factor: 1 imperial gallon per hours equals 1,262.802778 cubic millimeter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) 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 seconds to imperial gallon per hours conversion exact?
Yes. Both cubic millimeter per seconds and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0007918892939 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.
