About Converting Cup per Hours to Teaspoon per Years
Cup 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 = cup per hours × 420759.36
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct cup per hours-to-teaspoon per years factor of 420759.36.
Simple example
1 cup/h × 420759.36 = 420,759.36 tsp/yr
1 cup per hours = 420,759.36 teaspoon per years.
Real-world example
60 cup/h × 420759.36 = 25,245,561.6 tsp/yr
60 cup per hours = 25,245,561.6 teaspoon per years.

Frequently asked questions
How many teaspoon per years are in 1 cup per hours?
1 cup per hours equals 420,759.36 teaspoon per years, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to teaspoon per years?

How do I convert teaspoon per years back to cup per hours?
Use the reverse factor: 1 teaspoon per years equals 0.0000023767 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/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 cup per hours to teaspoon per years conversion exact?
Yes. Both cup per hours and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 420759.36 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.
