About Converting Cup per Hours to Cubic inch per Hours
Cup per Hours and Cubic inch per Hours 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 hours = cup per hours × 14.4375
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 cubic inch per hours equals 4.551962e-9 base units, so dividing one by the other gives the direct cup per hours-to-cubic inch per hours factor of 14.4375.
Simple example
1 cup/h × 14.4375 = 14.4375 in3/h
1 cup per hours = 14.4375 cubic inch per hours.
Real-world example
60 cup/h × 14.4375 = 866.25 in3/h
60 cup per hours = 866.25 cubic inch per hours.

How do I convert cubic inch per hours back to cup per hours?
Use the reverse factor: 1 cubic inch per hours equals 0.0692640693 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/h) is a unit of flow rate.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
Is the cup per hours to cubic inch per hours conversion exact?
Yes. Both cup per hours and cubic inch per hours are defined by fixed standards rather than physical artifacts, so the factor of 14.4375 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.
