About Converting Gallon per Weeks to Decaliter per Years
Gallon per Weeks and Decaliter 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
decaliter per years = gallon per weeks × 19.751332336
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 base units, and 1 decaliter per years equals 3.168874e-10 base units, so dividing one by the other gives the direct gallon per weeks-to-decaliter per years factor of 19.751332336.
Simple example
1 gal/wk × 19.75133234 = 19.75133234 daL/yr
1 gallon per weeks = 19.75133234 decaliter per years.
Real-world example
60 gal/wk × 19.75133234 = 1,185.07994 daL/yr
60 gallon per weeks = 1,185.07994 decaliter per years.

What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
What is a decaliter per years?
Decaliter per Years (daL/yr) is a unit of flow rate.
Is the gallon per weeks to decaliter per years conversion exact?
Yes. Both gallon per weeks and decaliter per years are defined by fixed standards rather than physical artifacts, so the factor of 19.75133234 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.
