About Converting Teaspoon per Years to Cup per Days
Teaspoon per Years and Cup per Days 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 days = teaspoon per years × 0.0000570397293123
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 days equals 2.73829e-9 base units, so dividing one by the other gives the direct teaspoon per years-to-cup per days factor of 0.0000570397293123.
Simple example
1 tsp/yr × 0.00005703972931 = 0.0000570397 cup/d
1 teaspoon per years = 0.0000570397 cup per days.
Real-world example
60 tsp/yr × 0.00005703972931 = 0.0034223838 cup/d
60 teaspoon per years = 0.0034223838 cup per days.

What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the teaspoon per years to cup per days conversion exact?
Yes. Both teaspoon per years and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 0.00005703972931 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.
