About Converting Teaspoons per Millisecond to Cup per Seconds
Teaspoon per Millisecond and Cup 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
cup per seconds = teaspoons per millisecond × 20.8333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per millisecond equals 0.00492892159375 base units, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct teaspoon per millisecond-to-cup per seconds factor of 20.8333333333.
Simple example
1 tsp/ms × 20.83333333 = 20.83333333 cup/s
1 teaspoon per millisecond = 20.83333333 cup per seconds.
Real-world example
60 tsp/ms × 20.83333333 = 1,250 cup/s
60 teaspoons per millisecond = 1,250 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 teaspoon per millisecond?
1 teaspoon per millisecond equals 20.83333333 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per millisecond to cup per seconds?
Multiply the teaspoon per millisecond value by 20.83333333. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to teaspoon per millisecond?
Use the reverse factor: 1 cup per seconds equals 0.048 teaspoons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the teaspoon per millisecond to cup per seconds conversion exact?
Yes. Both teaspoon per millisecond and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 20.83333333 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.
