About Converting Milliliter per Hours to Teaspoon per Years
Milliliter per Hours 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 hours × 1778.44581888
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct milliliter per hours-to-teaspoon per years factor of 1778.44581888.
Simple example
1 mL/h × 1778.445819 = 1,778.445819 tsp/yr
1 milliliter per hours = 1,778.445819 teaspoon per years.
Real-world example
60 mL/h × 1778.445819 = 106,706.7491 tsp/yr
60 milliliter per hours = 106,706.7491 teaspoon per years.

Frequently asked questions
How many teaspoon per years are in 1 milliliter per hours?
1 milliliter per hours equals 1,778.445819 teaspoon per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to teaspoon per years?
Multiply the milliliter per hours value by 1778.445819. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per years back to milliliter per hours?
Use the reverse factor: 1 teaspoon per years equals 0.0005622887 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) 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 hours to teaspoon per years conversion exact?
Yes. Both milliliter per hours and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 1778.445819 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.
