About Converting Gallon per Days to Imperial gallon per Hours
Gallon 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 = gallon per days × 0.0346947576929
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct gallon per days-to-imperial gallon per hours factor of 0.0346947576929.
Simple example
1 gal/d × 0.03469475769 = 0.0346947577 imp gal/h
1 gallon per days = 0.0346947577 imperial gallon per hours.
Real-world example
60 gal/d × 0.03469475769 = 2.081685462 imp gal/h
60 gallon per days = 2.081685462 imperial gallon per hours.

What is a gallon per days?
Gallon per Days (gal/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 gallon per days to imperial gallon per hours conversion exact?
Yes. Both gallon per days and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.03469475769 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.
