About Converting Quart per Years to Imperial gallon per Weeks
Quart per Years and Imperial gallon per Weeks 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 weeks = quart per years × 0.00398962284811
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 weeks equals 7.516683e-9 base units, so dividing one by the other gives the direct quart per years-to-imperial gallon per weeks factor of 0.00398962284811.
Simple example
1 qt/yr × 0.003989622848 = 0.0039896228 imp gal/wk
1 quart per years = 0.0039896228 imperial gallon per weeks.
Real-world example
60 qt/yr × 0.003989622848 = 0.2393773709 imp gal/wk
60 quart per years = 0.2393773709 imperial gallon per weeks.

What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
What is a imperial gallon per weeks?
Imperial gallon per Weeks (imp gal/wk) is a unit of flow rate.
Is the quart per years to imperial gallon per weeks conversion exact?
Yes. Both quart per years and imperial gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.003989622848 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.
