About Converting Milliliter per Years to Teaspoon per Hours
Milliliter per Years and Teaspoon per Hours 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 hours = milliliter per years × 0.0000231449124225
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 hours equals 1.369145e-9 base units, so dividing one by the other gives the direct milliliter per years-to-teaspoon per hours factor of 0.0000231449124225.
Simple example
1 mL/yr × 0.00002314491242 = 0.0000231449 tsp/h
1 milliliter per years = 0.0000231449 teaspoon per hours.
Real-world example
60 mL/yr × 0.00002314491242 = 0.0013886947 tsp/h
60 milliliter per years = 0.0013886947 teaspoon per hours.

Frequently asked questions
How many teaspoon per hours are in 1 milliliter per years?
1 milliliter per years equals 0.0000231449 teaspoon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per years to teaspoon per hours?
Multiply the milliliter per years value by 0.00002314491242. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per hours back to milliliter per years?
Use the reverse factor: 1 teaspoon per hours equals 43,206.03948 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 hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
Is the milliliter per years to teaspoon per hours conversion exact?
Yes. Both milliliter per years and teaspoon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.00002314491242 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.
