About Converting Imperial gallon per Hours to Quart per Years
Imperial gallon per Hours and Quart per Years 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 years = imperial gallon per hours × 42109.243504
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 quart per years equals 2.998873e-11 base units, so dividing one by the other gives the direct imperial gallon per hours-to-quart per years factor of 42109.243504.
Simple example
1 imp gal/h × 42109.2435 = 42,109.2435 qt/yr
1 imperial gallon per hours = 42,109.2435 quart per years.
Real-world example
60 imp gal/h × 42109.2435 = 2,526,554.61 qt/yr
60 imperial gallon per hours = 2,526,554.61 quart per years.

What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
Is the imperial gallon per hours to quart per years conversion exact?
Yes. Both imperial gallon per hours and quart per years are defined by fixed standards rather than physical artifacts, so the factor of 42109.2435 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.
