About Converting Teaspoon per Years to Cup per Decades
Teaspoon per Years and Cup per Decades 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 decades = teaspoon per years × 0.208333333333
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 decades equals 7.497183e-13 base units, so dividing one by the other gives the direct teaspoon per years-to-cup per decades factor of 0.208333333333.
Simple example
1 tsp/yr × 0.2083333333 = 0.2083333333 cup/decade
1 teaspoon per years = 0.2083333333 cup per decades.
Real-world example
60 tsp/yr × 0.2083333333 = 12.5 cup/decade
60 teaspoon per years = 12.5 cup per decades.

Frequently asked questions
How many cup per decades are in 1 teaspoon per years?
1 teaspoon per years equals 0.2083333333 cup per decades, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to cup per decades?
Multiply the teaspoon per years value by 0.2083333333. The converter above does this instantly to whatever precision you set.
How do I convert cup per decades back to teaspoon per years?
Use the reverse factor: 1 cup per decades equals 4.8 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 decades?
Cup per Decades (cup/decade) is a unit of flow rate.
Is the teaspoon per years to cup per decades conversion exact?
Yes. Both teaspoon per years and cup per decades are defined by fixed standards rather than physical artifacts, so the factor of 0.2083333333 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.
