About Converting Teaspoon per Years to Cup per Weeks
Teaspoon per Years and Cup per Weeks 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 weeks = teaspoon per years × 0.000399278105186
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 weeks equals 3.911843e-10 base units, so dividing one by the other gives the direct teaspoon per years-to-cup per weeks factor of 0.000399278105186.
Simple example
1 tsp/yr × 0.0003992781052 = 0.0003992781 cup/wk
1 teaspoon per years = 0.0003992781 cup per weeks.
Real-world example
60 tsp/yr × 0.0003992781052 = 0.0239566863 cup/wk
60 teaspoon per years = 0.0239566863 cup per weeks.

What is a cup per weeks?
Cup per Weeks (cup/wk) is a unit of flow rate.
Is the teaspoon per years to cup per weeks conversion exact?
Yes. Both teaspoon per years and cup per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.0003992781052 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.
