About Converting Tablespoon per Hours to Cubic inch per Days
Tablespoon per Hours 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 = tablespoon per hours × 21.65625
This factor comes from each unit's defined relationship to the category's base unit: 1 tablespoon per hours equals 4.107435e-9 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct tablespoon per hours-to-cubic inch per days factor of 21.65625.
Simple example
1 tbsp/h × 21.65625 = 21.65625 in3/d
1 tablespoon per hours = 21.65625 cubic inch per days.
Real-world example
60 tbsp/h × 21.65625 = 1,299.375 in3/d
60 tablespoon per hours = 1,299.375 cubic inch per days.

What is a tablespoon per hours?
Tablespoon per Hours (tbsp/h) 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 tablespoon per hours to cubic inch per days conversion exact?
Yes. Both tablespoon per hours and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 21.65625 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.
