About Converting Gallon per Months to Liter per Years
Gallon per Months 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 months × 45.424941408
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per months equals 1.439459e-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 months-to-liter per years factor of 45.424941408.
Simple example
1 gal/mo × 45.42494141 = 45.42494141 L/yr
1 gallon per months = 45.42494141 liter per years.
Real-world example
60 gal/mo × 45.42494141 = 2,725.496484 L/yr
60 gallon per months = 2,725.496484 liter per years.

Frequently asked questions
How many liter per years are in 1 gallon per months?
1 gallon per months equals 45.42494141 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per months to liter per years?
Multiply the gallon per months value by 45.42494141. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to gallon per months?
Use the reverse factor: 1 liter per years equals 0.0220143377 gallon per months. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per months?
Gallon per Months (gal/mo) 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 months to liter per years conversion exact?
Yes. Both gallon per months and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 45.42494141 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.
