About Converting Gallon per Weeks to Gallon per Years
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 = gallon per weeks × 52.1775
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct gallon per weeks-to-gallon per years factor of 52.1775.
Simple example
1 gal/wk × 52.1775 = 52.1775 gal/yr
1 gallon per weeks = 52.1775 gallon per years.
Real-world example
60 gal/wk × 52.1775 = 3,130.65 gal/yr
60 gallon per weeks = 3,130.65 gallon per years.

What is a gallon per weeks?
Gallon per Weeks (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 gallon per weeks to gallon per years conversion exact?
Yes. Both gallon per weeks and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 52.1775 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.
