About Converting Cubic inch per Hours to Cup per Seconds
Cubic inch per Hours and Cup 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
cup per seconds = cubic inch per hours × 0.00001924001924
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 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct cubic inch per hours-to-cup per seconds factor of 0.00001924001924.
Simple example
1 in3/h × 0.00001924001924 = 0.00001924 cup/s
1 cubic inch per hours = 0.00001924 cup per seconds.
Real-world example
60 in3/h × 0.00001924001924 = 0.0011544012 cup/s
60 cubic inch per hours = 0.0011544012 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 cubic inch per hours?
1 cubic inch per hours equals 0.00001924 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to cup per seconds?
Multiply the cubic inch per hours value by 0.00001924001924. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to cubic inch per hours?
Use the reverse factor: 1 cup per seconds equals 51,975 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 cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the cubic inch per hours to cup per seconds conversion exact?
Yes. Both cubic inch per hours and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00001924001924 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.
