About Converting Cubic inch per Hours to Cubic inch per Seconds
Cubic inch per Hours 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 = cubic inch per hours × 0.000277777777778
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 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct cubic inch per hours-to-cubic inch per seconds factor of 0.000277777777778.
Simple example
1 in3/h × 0.0002777777778 = 0.0002777778 in3/s
1 cubic inch per hours = 0.0002777778 cubic inch per seconds.
Real-world example
60 in3/h × 0.0002777777778 = 0.0166666667 in3/s
60 cubic inch per hours = 0.0166666667 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 cubic inch per hours?
1 cubic inch per hours equals 0.0002777778 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to cubic inch per seconds?
Multiply the cubic inch per hours value by 0.0002777777778. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to cubic inch per hours?
Use the reverse factor: 1 cubic inch per seconds equals 3,600 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 cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the cubic inch per hours to cubic inch per seconds conversion exact?
Yes. Both cubic inch per hours and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002777777778 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.
