About Converting Cubic foot per Hours to Gallon per Seconds
Cubic foot per Hours and Gallon 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
gallon per seconds = cubic foot per hours × 0.00207792207792
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per hours equals 0.00000786579072 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic foot per hours-to-gallon per seconds factor of 0.00207792207792.
Simple example
1 ft3/h × 0.002077922078 = 0.0020779221 gal/s
1 cubic foot per hours = 0.0020779221 gallon per seconds.
Real-world example
60 ft3/h × 0.002077922078 = 0.1246753247 gal/s
60 cubic foot per hours = 0.1246753247 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic foot per hours?
1 cubic foot per hours equals 0.0020779221 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per hours to gallon per seconds?
Multiply the cubic foot per hours value by 0.002077922078. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic foot per hours?
Use the reverse factor: 1 gallon per seconds equals 481.25 cubic foot per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic foot per hours to gallon per seconds conversion exact?
Yes. Both cubic foot per hours and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.002077922078 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.
