About Converting Teaspoon per Days to Cubic inch per Days
Teaspoon per Days and Cubic inch per Days 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 days = teaspoon per days × 0.30078125
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct teaspoon per days-to-cubic inch per days factor of 0.30078125.
Simple example
1 tsp/d × 0.30078125 = 0.30078125 in3/d
1 teaspoon per days = 0.30078125 cubic inch per days.
Real-world example
60 tsp/d × 0.30078125 = 18.046875 in3/d
60 teaspoon per days = 18.046875 cubic inch per days.

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