About Converting Teaspoon per Hours to Cubic inch per Hours
Teaspoon per Hours and Cubic inch 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
cubic inch per hours = teaspoon per hours × 0.30078125
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per hours equals 1.369145e-9 base units, and 1 cubic inch per hours equals 4.551962e-9 base units, so dividing one by the other gives the direct teaspoon per hours-to-cubic inch per hours factor of 0.30078125.
Simple example
1 tsp/h × 0.30078125 = 0.30078125 in3/h
1 teaspoon per hours = 0.30078125 cubic inch per hours.
Real-world example
60 tsp/h × 0.30078125 = 18.046875 in3/h
60 teaspoon per hours = 18.046875 cubic inch per hours.

How do I convert cubic inch per hours back to teaspoon per hours?
Use the reverse factor: 1 cubic inch per hours equals 3.324675325 teaspoon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
Is the teaspoon per hours to cubic inch per hours conversion exact?
Yes. Both teaspoon per hours and cubic inch per hours 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.
