About Converting Imperial gallon per Weeks to Gallon per Years
Imperial gallon per Weeks and 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
gallon per years = imperial gallon per weeks × 62.662564738
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 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct imperial gallon per weeks-to-gallon per years factor of 62.662564738.
Simple example
1 imp gal/wk × 62.66256474 = 62.66256474 gal/yr
1 imperial gallon per weeks = 62.66256474 gallon per years.
Real-world example
60 imp gal/wk × 62.66256474 = 3,759.753884 gal/yr
60 imperial gallon per weeks = 3,759.753884 gallon 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 gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the imperial gallon per weeks to gallon per years conversion exact?
Yes. Both imperial gallon per weeks and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 62.66256474 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.
