About Converting Cup per Days to Teaspoon per Seconds
Cup per Days and Teaspoon per Seconds 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
teaspoon per seconds = cup per days × 0.000555555555556
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 teaspoon per seconds equals 0.00000492892159375 base units, so dividing one by the other gives the direct cup per days-to-teaspoon per seconds factor of 0.000555555555556.
Simple example
1 cup/d × 0.0005555555556 = 0.0005555556 tsp/s
1 cup per days = 0.0005555556 teaspoon per seconds.
Real-world example
60 cup/d × 0.0005555555556 = 0.0333333333 tsp/s
60 cup per days = 0.0333333333 teaspoon per seconds.

Frequently asked questions
How many teaspoon per seconds are in 1 cup per days?
1 cup per days equals 0.0005555556 teaspoon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to teaspoon per seconds?
Multiply the cup per days value by 0.0005555555556. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per seconds back to cup per days?
Use the reverse factor: 1 teaspoon per seconds equals 1,800 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
Is the cup per days to teaspoon per seconds conversion exact?
Yes. Both cup per days and teaspoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0005555555556 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.
