About Converting Teaspoon per Seconds to Deciliter per Years
Teaspoon 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 = teaspoon per seconds × 1555417.42146
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 deciliter per years equals 3.168874e-12 base units, so dividing one by the other gives the direct teaspoon per seconds-to-deciliter per years factor of 1555417.42146.
Simple example
1 tsp/s × 1555417.421 = 1,555,417.421 dL/yr
1 teaspoon per seconds = 1,555,417.421 deciliter per years.
Real-world example
60 tsp/s × 1555417.421 = 93,325,045.29 dL/yr
60 teaspoon per seconds = 93,325,045.29 deciliter per years.

Frequently asked questions
How many deciliter per years are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 1,555,417.421 deciliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to deciliter per years?
Multiply the teaspoon per seconds value by 1555417.421. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per years back to teaspoon per seconds?
Use the reverse factor: 1 deciliter per years equals 6.429142e-7 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/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 teaspoon per seconds to deciliter per years conversion exact?
Yes. Both teaspoon per seconds and deciliter per years are defined by fixed standards rather than physical artifacts, so the factor of 1555417.421 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.
