About Converting Cubic inch per Days to Teaspoon per Seconds
Cubic inch per Days and Teaspoon per Seconds 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 seconds = cubic inch per days × 0.00003848003848
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 seconds equals 0.00000492892159375 base units, so dividing one by the other gives the direct cubic inch per days-to-teaspoon per seconds factor of 0.00003848003848.
Simple example
1 in3/d × 0.00003848003848 = 0.00003848 tsp/s
1 cubic inch per days = 0.00003848 teaspoon per seconds.
Real-world example
60 in3/d × 0.00003848003848 = 0.0023088023 tsp/s
60 cubic inch per days = 0.0023088023 teaspoon per seconds.

How do I convert teaspoon per seconds back to cubic inch per days?
Use the reverse factor: 1 teaspoon per seconds equals 25,987.5 cubic inch per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
Is the cubic inch per days to teaspoon per seconds conversion exact?
Yes. Both cubic inch per days and teaspoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00003848003848 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.
