About Converting Gallon per Years to Liter per Days
Gallon per Years and Liter per Days 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 days = gallon per years × 0.0103641054478
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 liter per days equals 1.157407e-8 base units, so dividing one by the other gives the direct gallon per years-to-liter per days factor of 0.0103641054478.
Simple example
1 gal/yr × 0.01036410545 = 0.0103641055 L/d
1 gallon per years = 0.0103641055 liter per days.
Real-world example
60 gal/yr × 0.01036410545 = 0.6218463269 L/d
60 gallon per years = 0.6218463269 liter per days.

Frequently asked questions
How many liter per days are in 1 gallon per years?
1 gallon per years equals 0.0103641055 liter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to liter per days?
Multiply the gallon per years value by 0.01036410545. The converter above does this instantly to whatever precision you set.
How do I convert liter per days back to gallon per years?
Use the reverse factor: 1 liter per days equals 96.48686083 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a liter per days?
Liter per Days (L/d) is a unit of flow rate.
Is the gallon per years to liter per days conversion exact?
Yes. Both gallon per years and liter per days are defined by fixed standards rather than physical artifacts, so the factor of 0.01036410545 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.
