About Converting Deciliter per Days to Imperial gallon per Years
Deciliter per Days and Imperial 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
imperial gallon per years = deciliter per days × 8.03421181719
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 imperial gallon per years equals 1.440599e-10 base units, so dividing one by the other gives the direct deciliter per days-to-imperial gallon per years factor of 8.03421181719.
Simple example
1 dL/d × 8.034211817 = 8.034211817 imp gal/yr
1 deciliter per days = 8.034211817 imperial gallon per years.
Real-world example
60 dL/d × 8.034211817 = 482.052709 imp gal/yr
60 deciliter per days = 482.052709 imperial gallon per years.

How do I convert imperial gallon per years back to deciliter per days?
Use the reverse factor: 1 imperial gallon per years equals 0.1244677167 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 imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the deciliter per days to imperial gallon per years conversion exact?
Yes. Both deciliter per days and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 8.034211817 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.
