About Converting Teaspoon per Years to Cup per Years
Teaspoon per Years and Cup 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
cup per years = teaspoon per years × 0.0208333333333
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 years equals 7.497183e-12 base units, so dividing one by the other gives the direct teaspoon per years-to-cup per years factor of 0.0208333333333.
Simple example
1 tsp/yr × 0.02083333333 = 0.0208333333 cup/yr
1 teaspoon per years = 0.0208333333 cup per years.
Real-world example
60 tsp/yr × 0.02083333333 = 1.25 cup/yr
60 teaspoon per years = 1.25 cup per years.

How do I convert cup per years back to teaspoon per years?
Use the reverse factor: 1 cup per years equals 48 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 cup per years?
Cup per Years (cup/yr) is a unit of flow rate.
Is the teaspoon per years to cup per years conversion exact?
Yes. Both teaspoon per years and cup per years are defined by fixed standards rather than physical artifacts, so the factor of 0.02083333333 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.
