About Converting Imperial gallon per Hours to Cup per Hours
Imperial gallon per Hours and Cup 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
cup per hours = imperial gallon per hours × 19.2151988081
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 cup per hours equals 6.571895e-8 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cup per hours factor of 19.2151988081.
Simple example
1 imp gal/h × 19.21519881 = 19.21519881 cup/h
1 imperial gallon per hours = 19.21519881 cup per hours.
Real-world example
60 imp gal/h × 19.21519881 = 1,152.911928 cup/h
60 imperial gallon per hours = 1,152.911928 cup per hours.

What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a cup per hours?
Cup per Hours (cup/h) is a unit of flow rate.
Is the imperial gallon per hours to cup per hours conversion exact?
Yes. Both imperial gallon per hours and cup per hours are defined by fixed standards rather than physical artifacts, so the factor of 19.21519881 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.
