About Converting Teaspoon per Minutes to Cubic inch per Hours
Teaspoon per Minutes 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 minutes × 18.046875
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per minutes equals 8.214869e-8 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 minutes-to-cubic inch per hours factor of 18.046875.
Simple example
1 tsp/min × 18.046875 = 18.046875 in3/h
1 teaspoon per minutes = 18.046875 cubic inch per hours.
Real-world example
60 tsp/min × 18.046875 = 1,082.8125 in3/h
60 teaspoon per minutes = 1,082.8125 cubic inch per hours.

What is a teaspoon per minutes?
Teaspoon per Minutes (tsp/min) 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 minutes to cubic inch per hours conversion exact?
Yes. Both teaspoon per minutes and cubic inch per hours 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.
