About Converting Teaspoon per Hours to Deciliter per Years
Teaspoon per Hours 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 hours × 432.060394849
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per hours equals 1.369145e-9 base units, and 1 deciliter per years equals 3.168874e-12 base units, so dividing one by the other gives the direct teaspoon per hours-to-deciliter per years factor of 432.060394849.
Simple example
1 tsp/h × 432.0603948 = 432.0603948 dL/yr
1 teaspoon per hours = 432.0603948 deciliter per years.
Real-world example
60 tsp/h × 432.0603948 = 25,923.62369 dL/yr
60 teaspoon per hours = 25,923.62369 deciliter per years.

Frequently asked questions
How many deciliter per years are in 1 teaspoon per hours?
1 teaspoon per hours equals 432.0603948 deciliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to deciliter per years?
Multiply the teaspoon per hours value by 432.0603948. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per years back to teaspoon per hours?
Use the reverse factor: 1 deciliter per years equals 0.0023144912 teaspoon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) 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 hours to deciliter per years conversion exact?
Yes. Both teaspoon per hours and deciliter per years are defined by fixed standards rather than physical artifacts, so the factor of 432.0603948 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.
