About Converting Teaspoon per Days to Cups per Fortnight
Teaspoon per Days and Cup per Fortnight 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
cups per fortnight = teaspoon per days × 0.291666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 cup per fortnight equals 1.955921e-10 base units, so dividing one by the other gives the direct teaspoon per days-to-cup per fortnight factor of 0.291666666667.
Simple example
1 tsp/d × 0.2916666667 = 0.2916666667 cup/fn
1 teaspoon per days = 0.2916666667 cups per fortnight.
Real-world example
60 tsp/d × 0.2916666667 = 17.5 cup/fn
60 teaspoon per days = 17.5 cups per fortnight.

Frequently asked questions
How many cups per fortnight are in 1 teaspoon per days?
1 teaspoon per days equals 0.2916666667 cups per fortnight, using the exact defined conversion factor rather than an estimate.

How do I convert cup per fortnight back to teaspoon per days?
Use the reverse factor: 1 cup per fortnight equals 3.428571429 teaspoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
What is a cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
Is the teaspoon per days to cup per fortnight conversion exact?
Yes. Both teaspoon per days and cup per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.2916666667 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.
