About Converting Gallon per Days to Liter per Years
Gallon per Days 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 days × 1382.59326352
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct gallon per days-to-liter per years factor of 1382.59326352.
Simple example
1 gal/d × 1382.593264 = 1,382.593264 L/yr
1 gallon per days = 1,382.593264 liter per years.
Real-world example
60 gal/d × 1382.593264 = 82,955.59581 L/yr
60 gallon per days = 82,955.59581 liter per years.

Frequently asked questions
How many liter per years are in 1 gallon per days?
1 gallon per days equals 1,382.593264 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to liter per years?
Multiply the gallon per days value by 1382.593264. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to gallon per days?
Use the reverse factor: 1 liter per years equals 0.0007232785 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) 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 days to liter per years conversion exact?
Yes. Both gallon per days and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 1382.593264 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.
