About Converting Teaspoon per Seconds to Cubic inches per Millisecond
Teaspoon per Seconds and Cubic inch per Millisecond 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 inches per millisecond = teaspoon per seconds × 0.00030078125
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 millisecond equals 0.016387064 base units, so dividing one by the other gives the direct teaspoon per seconds-to-cubic inch per millisecond factor of 0.00030078125.
Simple example
1 tsp/s × 0.00030078125 = 0.0003007813 in3/ms
1 teaspoon per seconds = 0.0003007813 cubic inches per millisecond.
Real-world example
60 tsp/s × 0.00030078125 = 0.018046875 in3/ms
60 teaspoon per seconds = 0.018046875 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 0.0003007813 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to cubic inch per millisecond?
Multiply the teaspoon per seconds value by 0.00030078125. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to teaspoon per seconds?
Use the reverse factor: 1 cubic inch per millisecond equals 3,324.675325 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 millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the teaspoon per seconds to cubic inch per millisecond conversion exact?
Yes. Both teaspoon per seconds and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00030078125 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.
