About Converting Fluid ounce per Hours to Gallon per Hours
Fluid ounce per Hours and Gallon 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
gallon per hours = fluid ounce per hours × 0.0078125
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per hours equals 8.214869e-9 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct fluid ounce per hours-to-gallon per hours factor of 0.0078125.
Simple example
1 fl oz/h × 0.0078125 = 0.0078125 gal/h
1 fluid ounce per hours = 0.0078125 gallon per hours.
Real-world example
60 fl oz/h × 0.0078125 = 0.46875 gal/h
60 fluid ounce per hours = 0.46875 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 fluid ounce per hours?
1 fluid ounce per hours equals 0.0078125 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per hours to gallon per hours?

How do I convert gallon per hours back to fluid ounce per hours?
Use the reverse factor: 1 gallon per hours equals 128 fluid ounce per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per hours?
Fluid ounce per Hours (fl oz/h) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the fluid ounce per hours to gallon per hours conversion exact?
Yes. Both fluid ounce per hours and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0078125 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.
