About Converting Quart per Minutes to Imperial gallon per Hours
Quart per Minutes 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 minutes × 12.4901127694
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per minutes equals 0.0000157725491 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct quart per minutes-to-imperial gallon per hours factor of 12.4901127694.
Simple example
1 qt/min × 12.49011277 = 12.49011277 imp gal/h
1 quart per minutes = 12.49011277 imperial gallon per hours.
Real-world example
60 qt/min × 12.49011277 = 749.4067662 imp gal/h
60 quart per minutes = 749.4067662 imperial gallon per hours.

What is a quart per minutes?
Quart per Minutes (qt/min) 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 minutes to imperial gallon per hours conversion exact?
Yes. Both quart per minutes and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 12.49011277 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.
