About Converting Deciliter per Seconds to Deciliter per Years
Deciliter per Seconds and Deciliter 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
deciliter per years = deciliter per seconds × 31556952
This factor comes from each unit's defined relationship to the category's base unit: 1 deciliter per seconds equals 0.0001 base units, and 1 deciliter per years equals 3.168874e-12 base units, so dividing one by the other gives the direct deciliter per seconds-to-deciliter per years factor of 31556952.
Simple example
1 dL/s × 31556952 = 31,556,952 dL/yr
1 deciliter per seconds = 31,556,952 deciliter per years.
Real-world example
60 dL/s × 31556952 = 1,893,417,120 dL/yr
60 deciliter per seconds = 1,893,417,120 deciliter per years.

Reverse conversion: Deciliter per Years to Deciliter per Seconds
1 dL/yr × 3.168874e-8 = 3.168874e-8 dL/s
1 deciliter per years = 3.168874e-8 deciliter per seconds.
deciliter per seconds = deciliter per years × 3.168874e-8

Frequently asked questions
How many deciliter per years are in 1 deciliter per seconds?
1 deciliter per seconds equals 31,556,952 deciliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert deciliter per seconds to deciliter per years?
Multiply the deciliter per seconds value by 31556952. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per years back to deciliter per seconds?
Use the reverse factor: 1 deciliter per years equals 3.168874e-8 deciliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciliter per seconds?
Deciliter per Seconds (dL/s) is a unit of flow rate.
What is a deciliter per years?
Deciliter per Years (dL/yr) is a unit of flow rate.
Is the deciliter per seconds to deciliter per years conversion exact?
Yes. Both deciliter per seconds and deciliter per years are defined by fixed standards rather than physical artifacts, so the factor of 31556952 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.
