About Converting Cup per Days to Imperial gallon per Hours
Cup per Days 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 = cup per days × 0.0021684223558
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cup per days-to-imperial gallon per hours factor of 0.0021684223558.
Simple example
1 cup/d × 0.002168422356 = 0.0021684224 imp gal/h
1 cup per days = 0.0021684224 imperial gallon per hours.
Real-world example
60 cup/d × 0.002168422356 = 0.1301053413 imp gal/h
60 cup per days = 0.1301053413 imperial gallon per hours.

What is a cup per days?
Cup per Days (cup/d) 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 cup per days to imperial gallon per hours conversion exact?
Yes. Both cup per days and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.002168422356 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.
