About Converting Cup per Seconds to Teaspoon per Hours
Cup per Seconds and Teaspoon per Hours 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 hours = cup per seconds × 172800
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per seconds equals 0.0002365882365 base units, and 1 teaspoon per hours equals 1.369145e-9 base units, so dividing one by the other gives the direct cup per seconds-to-teaspoon per hours factor of 172800.
Simple example
1 cup/s × 172800 = 172,800 tsp/h
1 cup per seconds = 172,800 teaspoon per hours.
Real-world example
60 cup/s × 172800 = 10,368,000 tsp/h
60 cup per seconds = 10,368,000 teaspoon per hours.

Frequently asked questions
How many teaspoon per hours are in 1 cup per seconds?
1 cup per seconds equals 172,800 teaspoon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cup per seconds to teaspoon per hours?
Multiply the cup per seconds value by 172800. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per hours back to cup per seconds?
Use the reverse factor: 1 teaspoon per hours equals 0.000005787 cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
Is the cup per seconds to teaspoon per hours conversion exact?
Yes. Both cup per seconds and teaspoon per hours are defined by fixed standards rather than physical artifacts, so the factor of 172800 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.
