About Converting Cubic inch per Minutes to Imperial gallon per Hours
Cubic inch per Minutes 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 inch per minutes × 0.216279008995
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per minutes equals 2.731177e-7 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic inch per minutes-to-imperial gallon per hours factor of 0.216279008995.
Simple example
1 in3/min × 0.216279009 = 0.216279009 imp gal/h
1 cubic inch per minutes = 0.216279009 imperial gallon per hours.
Real-world example
60 in3/min × 0.216279009 = 12.97674054 imp gal/h
60 cubic inch per minutes = 12.97674054 imperial gallon per hours.

What is a cubic inch per minutes?
Cubic inch per Minutes (in3/min) 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 inch per minutes to imperial gallon per hours conversion exact?
Yes. Both cubic inch per minutes and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.216279009 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.
