About Converting Imperial gallon per Weeks to Quart per Years
Imperial gallon per Weeks 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 weeks × 250.650258952
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per weeks equals 7.516683e-9 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 weeks-to-quart per years factor of 250.650258952.
Simple example
1 imp gal/wk × 250.650259 = 250.650259 qt/yr
1 imperial gallon per weeks = 250.650259 quart per years.
Real-world example
60 imp gal/wk × 250.650259 = 15,039.01554 qt/yr
60 imperial gallon per weeks = 15,039.01554 quart per years.

What is a imperial gallon per weeks?
Imperial gallon per Weeks (imp gal/wk) 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 weeks to quart per years conversion exact?
Yes. Both imperial gallon per weeks and quart per years are defined by fixed standards rather than physical artifacts, so the factor of 250.650259 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.
