About Converting Teaspoon per Seconds to Cubic inch per Seconds
Teaspoon per Seconds and Cubic inch 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
cubic inch per seconds = teaspoon per seconds × 0.30078125
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 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct teaspoon per seconds-to-cubic inch per seconds factor of 0.30078125.
Simple example
1 tsp/s × 0.30078125 = 0.30078125 in3/s
1 teaspoon per seconds = 0.30078125 cubic inch per seconds.
Real-world example
60 tsp/s × 0.30078125 = 18.046875 in3/s
60 teaspoon per seconds = 18.046875 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 0.30078125 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to cubic inch per seconds?
Multiply the teaspoon per seconds value by 0.30078125. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to teaspoon per seconds?
Use the reverse factor: 1 cubic inch per seconds equals 3.324675325 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 cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the teaspoon per seconds to cubic inch per seconds conversion exact?
Yes. Both teaspoon per seconds and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.30078125 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.
