About Converting Cubic inch per Days to Teaspoon per Hours
Cubic inch per Days and Teaspoon 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
teaspoon per hours = cubic inch per days × 0.138528138528
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per days equals 1.896651e-10 base units, and 1 teaspoon per hours equals 1.369145e-9 base units, so dividing one by the other gives the direct cubic inch per days-to-teaspoon per hours factor of 0.138528138528.
Simple example
1 in3/d × 0.1385281385 = 0.1385281385 tsp/h
1 cubic inch per days = 0.1385281385 teaspoon per hours.
Real-world example
60 in3/d × 0.1385281385 = 8.311688312 tsp/h
60 cubic inch per days = 8.311688312 teaspoon per hours.

What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
Is the cubic inch per days to teaspoon per hours conversion exact?
Yes. Both cubic inch per days and teaspoon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.1385281385 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.
