About Converting Cubic inch per Seconds to Cubic foot per Hours
Cubic inch per Seconds and Cubic foot 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 foot per hours = cubic inch per seconds × 2.08333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 cubic foot per hours equals 0.00000786579072 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cubic foot per hours factor of 2.08333333333.
Simple example
1 in3/s × 2.083333333 = 2.083333333 ft3/h
1 cubic inch per seconds = 2.083333333 cubic foot per hours.
Real-world example
60 in3/s × 2.083333333 = 125 ft3/h
60 cubic inch per seconds = 125 cubic foot per hours.

Multiply the cubic inch per seconds value by 2.083333333. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per hours back to cubic inch per seconds?
Use the reverse factor: 1 cubic foot per hours equals 0.48 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
Is the cubic inch per seconds to cubic foot per hours conversion exact?
Yes. Both cubic inch per seconds and cubic foot per hours are defined by fixed standards rather than physical artifacts, so the factor of 2.083333333 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.
