About Converting Liter per Years to Gallon per Years
Liter per Years 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 = liter per years × 0.264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per years equals 3.168874e-11 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct liter per years-to-gallon per years factor of 0.264172052358.
Simple example
1 L/yr × 0.2641720524 = 0.2641720524 gal/yr
1 liter per years = 0.2641720524 gallon per years.
Real-world example
60 L/yr × 0.2641720524 = 15.85032314 gal/yr
60 liter per years = 15.85032314 gallon per years.

Frequently asked questions
How many gallon per years are in 1 liter per years?
1 liter per years equals 0.2641720524 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per years to gallon per years?
Multiply the liter per years value by 0.2641720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to liter per years?
Use the reverse factor: 1 gallon per years equals 3.785411784 liter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per years?
Liter per Years (L/yr) 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 liter per years to gallon per years conversion exact?
Yes. Both liter per years and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.2641720524 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.
