About Converting Imperial gallon per Days to Gallon per Hours
Imperial gallon per Days and 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
gallon per hours = imperial gallon per days × 0.0500395802294
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct imperial gallon per days-to-gallon per hours factor of 0.0500395802294.
Simple example
1 imp gal/d × 0.05003958023 = 0.0500395802 gal/h
1 imperial gallon per days = 0.0500395802 gallon per hours.
Real-world example
60 imp gal/d × 0.05003958023 = 3.002374814 gal/h
60 imperial gallon per days = 3.002374814 gallon per hours.

What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the imperial gallon per days to gallon per hours conversion exact?
Yes. Both imperial gallon per days and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.05003958023 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.
