About Converting Teaspoon per Seconds to Cubic inch per Minutes
Teaspoon per Seconds and Cubic inch per Minutes 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 minutes = teaspoon per seconds × 18.046875
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 minutes equals 2.731177e-7 base units, so dividing one by the other gives the direct teaspoon per seconds-to-cubic inch per minutes factor of 18.046875.
Simple example
1 tsp/s × 18.046875 = 18.046875 in3/min
1 teaspoon per seconds = 18.046875 cubic inch per minutes.
Real-world example
60 tsp/s × 18.046875 = 1,082.8125 in3/min
60 teaspoon per seconds = 1,082.8125 cubic inch per minutes.

Frequently asked questions
How many cubic inch per minutes are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 18.046875 cubic inch per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to cubic inch per minutes?
Multiply the teaspoon per seconds value by 18.046875. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per minutes back to teaspoon per seconds?
Use the reverse factor: 1 cubic inch per minutes equals 0.0554112554 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 minutes?
Cubic inch per Minutes (in3/min) is a unit of flow rate.
Is the teaspoon per seconds to cubic inch per minutes conversion exact?
Yes. Both teaspoon per seconds and cubic inch per minutes are defined by fixed standards rather than physical artifacts, so the factor of 18.046875 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.
