About Converting Gallon per Weeks to Liter per Years
Gallon per Weeks and Liter 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
liter per years = gallon per weeks × 197.51332336
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 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct gallon per weeks-to-liter per years factor of 197.51332336.
Simple example
1 gal/wk × 197.5133234 = 197.5133234 L/yr
1 gallon per weeks = 197.5133234 liter per years.
Real-world example
60 gal/wk × 197.5133234 = 11,850.7994 L/yr
60 gallon per weeks = 11,850.7994 liter per years.

How do I convert liter per years back to gallon per weeks?
Use the reverse factor: 1 liter per years equals 0.0050629496 gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the gallon per weeks to liter per years conversion exact?
Yes. Both gallon per weeks and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 197.5133234 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.
