About Converting Quart per Years to Imperial gallon per Years
Quart per Years and Imperial gallon 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
imperial gallon per years = quart per years × 0.208168546157
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per years equals 2.998873e-11 base units, and 1 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct quart per years-to-imperial gallon per years factor of 0.208168546157.
Simple example
1 qt/yr × 0.2081685462 = 0.2081685462 imp gal/yr
1 quart per years = 0.2081685462 imperial gallon per years.
Real-world example
60 qt/yr × 0.2081685462 = 12.49011277 imp gal/yr
60 quart per years = 12.49011277 imperial gallon per years.

What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the quart per years to imperial gallon per years conversion exact?
Yes. Both quart per years and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.2081685462 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.
