About Converting Teaspoon per Years to Milliliter per Hours
Teaspoon per Years and Milliliter 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
milliliter per hours = teaspoon per years × 0.000562288707018
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 hours equals 2.777778e-10 base units, so dividing one by the other gives the direct teaspoon per years-to-milliliter per hours factor of 0.000562288707018.
Simple example
1 tsp/yr × 0.000562288707 = 0.0005622887 mL/h
1 teaspoon per years = 0.0005622887 milliliter per hours.
Real-world example
60 tsp/yr × 0.000562288707 = 0.0337373224 mL/h
60 teaspoon per years = 0.0337373224 milliliter per hours.

Frequently asked questions
How many milliliter per hours are in 1 teaspoon per years?
1 teaspoon per years equals 0.0005622887 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to milliliter per hours?
Multiply the teaspoon per years value by 0.000562288707. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to teaspoon per years?
Use the reverse factor: 1 milliliter per hours equals 1,778.445819 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 hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
Is the teaspoon per years to milliliter per hours conversion exact?
Yes. Both teaspoon per years and milliliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.000562288707 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.
