About Converting Fluid ounce per Hours to Gallon per Minutes
Fluid ounce per Hours and Gallon per Minutes 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 minutes = fluid ounce per hours × 0.000130208333333
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 minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct fluid ounce per hours-to-gallon per minutes factor of 0.000130208333333.
Simple example
1 fl oz/h × 0.0001302083333 = 0.0001302083 gal/min
1 fluid ounce per hours = 0.0001302083 gallon per minutes.
Real-world example
60 fl oz/h × 0.0001302083333 = 0.0078125 gal/min
60 fluid ounce per hours = 0.0078125 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 fluid ounce per hours?
1 fluid ounce per hours equals 0.0001302083 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per hours to gallon per minutes?
Multiply the fluid ounce per hours value by 0.0001302083333. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to fluid ounce per hours?
Use the reverse factor: 1 gallon per minutes equals 7,680 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 minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the fluid ounce per hours to gallon per minutes conversion exact?
Yes. Both fluid ounce per hours and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0001302083333 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.
