About Converting Gallon per Days to Imperial quart per Hours
Gallon per Days and Imperial 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
imperial quart per hours = gallon per days × 0.138779030771
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 quart per hours equals 3.157007e-7 base units, so dividing one by the other gives the direct gallon per days-to-imperial quart per hours factor of 0.138779030771.
Simple example
1 gal/d × 0.1387790308 = 0.1387790308 imp qt/h
1 gallon per days = 0.1387790308 imperial quart per hours.
Real-world example
60 gal/d × 0.1387790308 = 8.326741846 imp qt/h
60 gallon per days = 8.326741846 imperial quart per hours.

What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
Is the gallon per days to imperial quart per hours conversion exact?
Yes. Both gallon per days and imperial quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.1387790308 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.
