About Converting Quart per Days to Imperial gallon per Hours
Quart 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 = quart per days × 0.00867368942322
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct quart per days-to-imperial gallon per hours factor of 0.00867368942322.
Simple example
1 qt/d × 0.008673689423 = 0.0086736894 imp gal/h
1 quart per days = 0.0086736894 imperial gallon per hours.
Real-world example
60 qt/d × 0.008673689423 = 0.5204213654 imp gal/h
60 quart per days = 0.5204213654 imperial gallon per hours.

What is a quart per days?
Quart per Days (qt/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 quart per days to imperial gallon per hours conversion exact?
Yes. Both quart per days and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.008673689423 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.
