About Converting Gallon per Hours to Cubic foot per Hours
Gallon per Hours 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 = gallon per hours × 0.133680555556
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 cubic foot per hours equals 0.00000786579072 base units, so dividing one by the other gives the direct gallon per hours-to-cubic foot per hours factor of 0.133680555556.
Simple example
1 gal/h × 0.1336805556 = 0.1336805556 ft3/h
1 gallon per hours = 0.1336805556 cubic foot per hours.
Real-world example
60 gal/h × 0.1336805556 = 8.020833333 ft3/h
60 gallon per hours = 8.020833333 cubic foot per hours.

What is a gallon per hours?
Gallon per Hours (gal/h) 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 gallon per hours to cubic foot per hours conversion exact?
Yes. Both gallon per hours and cubic foot per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.1336805556 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.
