About Converting Milliliter per Years to Teaspoon per Years
Milliliter per Years and Teaspoon 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
teaspoon per years = milliliter per years × 0.202884136211
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per years equals 3.168874e-14 base units, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct milliliter per years-to-teaspoon per years factor of 0.202884136211.
Simple example
1 mL/yr × 0.2028841362 = 0.2028841362 tsp/yr
1 milliliter per years = 0.2028841362 teaspoon per years.
Real-world example
60 mL/yr × 0.2028841362 = 12.17304817 tsp/yr
60 milliliter per years = 12.17304817 teaspoon per years.

Frequently asked questions
How many teaspoon per years are in 1 milliliter per years?
1 milliliter per years equals 0.2028841362 teaspoon per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per years to teaspoon per years?
Multiply the milliliter per years value by 0.2028841362. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per years back to milliliter per years?
Use the reverse factor: 1 teaspoon per years equals 4.928921594 milliliter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per years?
Milliliter per Years (mL/yr) is a unit of flow rate.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
Is the milliliter per years to teaspoon per years conversion exact?
Yes. Both milliliter per years and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 0.2028841362 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.
