About Converting Deciliter per Days to Gallon per Years
Deciliter per Days 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 = deciliter per days × 9.64868608334
This factor comes from each unit's defined relationship to the category's base unit: 1 deciliter per days equals 1.157407e-9 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct deciliter per days-to-gallon per years factor of 9.64868608334.
Simple example
1 dL/d × 9.648686083 = 9.648686083 gal/yr
1 deciliter per days = 9.648686083 gallon per years.
Real-world example
60 dL/d × 9.648686083 = 578.921165 gal/yr
60 deciliter per days = 578.921165 gallon per years.

Frequently asked questions
How many gallon per years are in 1 deciliter per days?
1 deciliter per days equals 9.648686083 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert deciliter per days to gallon per years?
Multiply the deciliter per days value by 9.648686083. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to deciliter per days?
Use the reverse factor: 1 gallon per years equals 0.1036410545 deciliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciliter per days?
Deciliter per Days (dL/d) 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 deciliter per days to gallon per years conversion exact?
Yes. Both deciliter per days and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 9.648686083 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.
