About Converting Gallon per Hours to Imperial fluid ounces per Millisecond
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 = gallon per hours × 0.0000370077415391
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 imperial fluid ounce per millisecond equals 0.0284130625 base units, so dividing one by the other gives the direct gallon per hours-to-imperial fluid ounce per millisecond factor of 0.0000370077415391.
Simple example
1 gal/h × 0.00003700774154 = 0.0000370077 imp fl oz/ms
1 gallon per hours = 0.0000370077 imperial fluid ounces per millisecond.
Real-world example
60 gal/h × 0.00003700774154 = 0.0022204645 imp fl oz/ms
60 gallon per hours = 0.0022204645 imperial fluid ounces per millisecond.

Frequently asked questions
How many imperial fluid ounces per millisecond are in 1 gallon per hours?
1 gallon per hours equals 0.0000370077 imperial fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to imperial fluid ounce per millisecond?
Multiply the gallon per hours value by 0.00003700774154. The converter above does this instantly to whatever precision you set.
How do I convert imperial fluid ounce per millisecond back to gallon per hours?
Use the reverse factor: 1 imperial fluid ounce per millisecond equals 27,021.37332 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (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 gallon per hours to imperial fluid ounce per millisecond conversion exact?
Yes. Both gallon per hours and imperial fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00003700774154 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.
