About Converting Teaspoon per Years to Deciliters per Millisecond
Teaspoon per Years and Deciliter per Millisecond 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
deciliters per millisecond = teaspoon per years × 1.561913e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per years equals 1.561913e-13 base units, and 1 deciliter per millisecond equals 0.1 base units, so dividing one by the other gives the direct teaspoon per years-to-deciliter per millisecond factor of 1.561913e-12.
Simple example
1 tsp/yr × 1.561913e-12 = 1.561913e-12 dL/ms
1 teaspoon per years = 1.561913e-12 deciliters per millisecond.
Real-world example
60 tsp/yr × 1.561913e-12 = 9.371478e-11 dL/ms
60 teaspoon per years = 9.371478e-11 deciliters per millisecond.

Frequently asked questions
How many deciliters per millisecond are in 1 teaspoon per years?
1 teaspoon per years equals 1.561913e-12 deciliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to deciliter per millisecond?
Multiply the teaspoon per years value by 1.561913e-12. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per millisecond back to teaspoon per years?
Use the reverse factor: 1 deciliter per millisecond equals 640,240,494,800 teaspoon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a deciliter per millisecond?
Deciliter per Millisecond (dL/ms) is a unit of flow rate.
Is the teaspoon per years to deciliter per millisecond conversion exact?
Yes. Both teaspoon per years and deciliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.561913e-12 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.
