About Converting Cubic inch per Hours to Tablespoon per Seconds
Cubic inch per Hours and Tablespoon 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
tablespoon per seconds = cubic inch per hours × 0.00030784030784
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 tablespoon per seconds equals 0.0000147867647813 base units, so dividing one by the other gives the direct cubic inch per hours-to-tablespoon per seconds factor of 0.00030784030784.
Simple example
1 in3/h × 0.0003078403078 = 0.0003078403 tbsp/s
1 cubic inch per hours = 0.0003078403 tablespoon per seconds.
Real-world example
60 in3/h × 0.0003078403078 = 0.0184704185 tbsp/s
60 cubic inch per hours = 0.0184704185 tablespoon per seconds.

Multiply the cubic inch per hours value by 0.0003078403078. The converter above does this instantly to whatever precision you set.
How do I convert tablespoon per seconds back to cubic inch per hours?
Use the reverse factor: 1 tablespoon per seconds equals 3,248.4375 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
What is a tablespoon per seconds?
Tablespoon per Seconds (tbsp/s) is a unit of flow rate.
Is the cubic inch per hours to tablespoon per seconds conversion exact?
Yes. Both cubic inch per hours and tablespoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0003078403078 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.
