About Converting Imperial fluid ounce per Hours to Gallon per Minutes
Imperial 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 = imperial fluid ounce per hours × 0.000125098950573
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial fluid ounce per hours equals 7.892517e-9 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct imperial fluid ounce per hours-to-gallon per minutes factor of 0.000125098950573.
Simple example
1 imp fl oz/h × 0.0001250989506 = 0.000125099 gal/min
1 imperial fluid ounce per hours = 0.000125099 gallon per minutes.
Real-world example
60 imp fl oz/h × 0.0001250989506 = 0.007505937 gal/min
60 imperial fluid ounce per hours = 0.007505937 gallon per minutes.

How do I convert gallon per minutes back to imperial fluid ounce per hours?
Use the reverse factor: 1 gallon per minutes equals 7,993.672172 imperial fluid ounce per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial fluid ounce per hours?
Imperial fluid ounce per Hours (imp 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 imperial fluid ounce per hours to gallon per minutes conversion exact?
Yes. Both imperial fluid ounce per hours and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0001250989506 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.
