About Converting Imperial gallon per Days to Quart per Hours
Imperial gallon per Days and Quart 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
quart per hours = imperial gallon per days × 0.200158320917
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 quart per hours equals 2.628758e-7 base units, so dividing one by the other gives the direct imperial gallon per days-to-quart per hours factor of 0.200158320917.
Simple example
1 imp gal/d × 0.2001583209 = 0.2001583209 qt/h
1 imperial gallon per days = 0.2001583209 quart per hours.
Real-world example
60 imp gal/d × 0.2001583209 = 12.00949926 qt/h
60 imperial gallon per days = 12.00949926 quart 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 quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the imperial gallon per days to quart per hours conversion exact?
Yes. Both imperial gallon per days and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.2001583209 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.
