About Converting Imperial gallon per Hours to Cup per Days
Imperial gallon per Hours and Cup per Days 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 days = imperial gallon per hours × 461.164771394
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 days equals 2.73829e-9 base units, so dividing one by the other gives the direct imperial gallon per hours-to-cup per days factor of 461.164771394.
Simple example
1 imp gal/h × 461.1647714 = 461.1647714 cup/d
1 imperial gallon per hours = 461.1647714 cup per days.
Real-world example
60 imp gal/h × 461.1647714 = 27,669.88628 cup/d
60 imperial gallon per hours = 27,669.88628 cup per days.

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 days?
Cup per Days (cup/d) is a unit of flow rate.
Is the imperial gallon per hours to cup per days conversion exact?
Yes. Both imperial gallon per hours and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 461.1647714 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.
