About Converting Cubic foot per Seconds to Cubic foot per Hours
Cubic foot 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
cubic foot per hours = cubic foot per seconds × 3600
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 cubic foot per hours equals 0.00000786579072 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic foot per hours factor of 3600.
Simple example
1 ft3/s × 3600 = 3,600 ft3/h
1 cubic foot per seconds = 3,600 cubic foot per hours.
Real-world example
60 ft3/s × 3600 = 216,000 ft3/h
60 cubic foot per seconds = 216,000 cubic foot per hours.

Frequently asked questions
How many cubic foot per hours are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 3,600 cubic foot per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic foot per hours?
Multiply the cubic foot per seconds value by 3600. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per hours back to cubic foot per seconds?
Use the reverse factor: 1 cubic foot per hours equals 0.0002777778 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
Is the cubic foot per seconds to cubic foot per hours conversion exact?
Yes. Both cubic foot per seconds and cubic foot per hours are defined by fixed standards rather than physical artifacts, so the factor of 3600 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
