About Converting Teaspoon per Years to Cup per Hours
Teaspoon per Years and Cup 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
cup per hours = teaspoon per years × 0.00000237665538801
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 cup per hours equals 6.571895e-8 base units, so dividing one by the other gives the direct teaspoon per years-to-cup per hours factor of 0.00000237665538801.
Simple example
1 tsp/yr × 0.000002376655388 = 0.0000023767 cup/h
1 teaspoon per years = 0.0000023767 cup per hours.
Real-world example
60 tsp/yr × 0.000002376655388 = 0.0001425993 cup/h
60 teaspoon per years = 0.0001425993 cup per hours.

What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a cup per hours?
Cup per Hours (cup/h) is a unit of flow rate.
Is the teaspoon per years to cup per hours conversion exact?
Yes. Both teaspoon per years and cup per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.000002376655388 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.
