About Converting Teaspoon per Days to Deciliter per Years
Teaspoon per Days 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 days × 18.0025164521
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 deciliter per years equals 3.168874e-12 base units, so dividing one by the other gives the direct teaspoon per days-to-deciliter per years factor of 18.0025164521.
Simple example
1 tsp/d × 18.00251645 = 18.00251645 dL/yr
1 teaspoon per days = 18.00251645 deciliter per years.
Real-world example
60 tsp/d × 18.00251645 = 1,080.150987 dL/yr
60 teaspoon per days = 1,080.150987 deciliter per years.

Frequently asked questions
How many deciliter per years are in 1 teaspoon per days?
1 teaspoon per days equals 18.00251645 deciliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per days to deciliter per years?
Multiply the teaspoon per days value by 18.00251645. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per years back to teaspoon per days?
Use the reverse factor: 1 deciliter per years equals 0.0555477898 teaspoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) 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 days to deciliter per years conversion exact?
Yes. Both teaspoon per days and deciliter per years are defined by fixed standards rather than physical artifacts, so the factor of 18.00251645 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.
