About Converting Teaspoon per Years to Milliliter per Days
Teaspoon per Years and Milliliter per Days 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
milliliter per days = teaspoon per years × 0.0134949289684
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 milliliter per days equals 1.157407e-11 base units, so dividing one by the other gives the direct teaspoon per years-to-milliliter per days factor of 0.0134949289684.
Simple example
1 tsp/yr × 0.01349492897 = 0.013494929 mL/d
1 teaspoon per years = 0.013494929 milliliter per days.
Real-world example
60 tsp/yr × 0.01349492897 = 0.8096957381 mL/d
60 teaspoon per years = 0.8096957381 milliliter per days.

Frequently asked questions
How many milliliter per days are in 1 teaspoon per years?
1 teaspoon per years equals 0.013494929 milliliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to milliliter per days?
Multiply the teaspoon per years value by 0.01349492897. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per days back to teaspoon per years?
Use the reverse factor: 1 milliliter per days equals 74.10190912 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 milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
Is the teaspoon per years to milliliter per days conversion exact?
Yes. Both teaspoon per years and milliliter per days are defined by fixed standards rather than physical artifacts, so the factor of 0.01349492897 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.
