About Converting Quart per Hours to Imperial gallon per Days
Quart per Hours and Imperial gallon 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
imperial gallon per days = quart per hours × 4.99604510777
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per hours equals 2.628758e-7 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct quart per hours-to-imperial gallon per days factor of 4.99604510777.
Simple example
1 qt/h × 4.996045108 = 4.996045108 imp gal/d
1 quart per hours = 4.996045108 imperial gallon per days.
Real-world example
60 qt/h × 4.996045108 = 299.7627065 imp gal/d
60 quart per hours = 299.7627065 imperial gallon per days.

What is a quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the quart per hours to imperial gallon per days conversion exact?
Yes. Both quart per hours and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 4.996045108 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.
