About Converting Teaspoon per Seconds to Cup per Days
Teaspoon per Seconds 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 seconds × 1800
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct teaspoon per seconds-to-cup per days factor of 1800.
Simple example
1 tsp/s × 1800 = 1,800 cup/d
1 teaspoon per seconds = 1,800 cup per days.
Real-world example
60 tsp/s × 1800 = 108,000 cup/d
60 teaspoon per seconds = 108,000 cup per days.

Frequently asked questions
How many cup per days are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 1,800 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to cup per days?
Multiply the teaspoon per seconds value by 1800. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to teaspoon per seconds?
Use the reverse factor: 1 cup per days equals 0.0005555556 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) 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 seconds to cup per days conversion exact?
Yes. Both teaspoon per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 1800 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.
