About Converting Teaspoon per Days to Cubic inch per Seconds
Teaspoon per Days and Cubic inch 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
cubic inch per seconds = teaspoon per days × 0.00000348126446759
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 seconds equals 0.000016387064 base units, so dividing one by the other gives the direct teaspoon per days-to-cubic inch per seconds factor of 0.00000348126446759.
Simple example
1 tsp/d × 0.000003481264468 = 0.0000034813 in3/s
1 teaspoon per days = 0.0000034813 cubic inch per seconds.
Real-world example
60 tsp/d × 0.000003481264468 = 0.0002088759 in3/s
60 teaspoon per days = 0.0002088759 cubic inch per seconds.

How do I convert cubic inch per seconds back to teaspoon per days?
Use the reverse factor: 1 cubic inch per seconds equals 287,251.9481 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 seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the teaspoon per days to cubic inch per seconds conversion exact?
Yes. Both teaspoon per days and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000003481264468 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.
