About Converting Fluid ounces per Millisecond to Gallon per Hours
Fluid ounce per Millisecond 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 ounces per millisecond × 28125
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per millisecond equals 0.0295735295625 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct fluid ounce per millisecond-to-gallon per hours factor of 28125.
Simple example
1 fl oz/ms × 28125 = 28,125 gal/h
1 fluid ounce per millisecond = 28,125 gallon per hours.
Real-world example
60 fl oz/ms × 28125 = 1,687,500 gal/h
60 fluid ounces per millisecond = 1,687,500 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 fluid ounce per millisecond?
1 fluid ounce per millisecond equals 28,125 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per millisecond to gallon per hours?
Multiply the fluid ounce per millisecond value by 28125. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to fluid ounce per millisecond?
Use the reverse factor: 1 gallon per hours equals 0.0000355556 fluid ounces per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) 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 millisecond to gallon per hours conversion exact?
Yes. Both fluid ounce per millisecond and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 28125 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.
