About Converting Imperial quart per Minutes to Gallon per Hours
Imperial quart per Minutes and 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
gallon per hours = imperial quart per minutes × 18.0142488826
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per minutes equals 0.0000189420416667 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct imperial quart per minutes-to-gallon per hours factor of 18.0142488826.
Simple example
1 imp qt/min × 18.01424888 = 18.01424888 gal/h
1 imperial quart per minutes = 18.01424888 gallon per hours.
Real-world example
60 imp qt/min × 18.01424888 = 1,080.854933 gal/h
60 imperial quart per minutes = 1,080.854933 gallon per hours.

What is a imperial quart per minutes?
Imperial quart per Minutes (imp qt/min) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the imperial quart per minutes to gallon per hours conversion exact?
Yes. Both imperial quart per minutes and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 18.01424888 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.
