About Converting Imperial gallon per Hours to Imperial fluid ounces per Millisecond
Imperial gallon per Hours and Imperial fluid ounce per Millisecond 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
imperial fluid ounces per millisecond = imperial gallon per hours × 0.0000444444444444
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 imperial fluid ounce per millisecond equals 0.0284130625 base units, so dividing one by the other gives the direct imperial gallon per hours-to-imperial fluid ounce per millisecond factor of 0.0000444444444444.
Simple example
1 imp gal/h × 0.00004444444444 = 0.0000444444 imp fl oz/ms
1 imperial gallon per hours = 0.0000444444 imperial fluid ounces per millisecond.
Real-world example
60 imp gal/h × 0.00004444444444 = 0.0026666667 imp fl oz/ms
60 imperial gallon per hours = 0.0026666667 imperial fluid ounces per millisecond.

Frequently asked questions
How many imperial fluid ounces per millisecond are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 0.0000444444 imperial fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to imperial fluid ounce per millisecond?
Multiply the imperial gallon per hours value by 0.00004444444444. The converter above does this instantly to whatever precision you set.
How do I convert imperial fluid ounce per millisecond back to imperial gallon per hours?
Use the reverse factor: 1 imperial fluid ounce per millisecond equals 22,500 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a imperial fluid ounce per millisecond?
Imperial fluid ounce per Millisecond (imp fl oz/ms) is a unit of flow rate.
Is the imperial gallon per hours to imperial fluid ounce per millisecond conversion exact?
Yes. Both imperial gallon per hours and imperial fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00004444444444 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.
