About Converting Gallons per Millisecond to Fluid ounces per Millisecond
Gallon per Millisecond and 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
fluid ounces per millisecond = gallons per millisecond × 128
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 fluid ounce per millisecond equals 0.0295735295625 base units, so dividing one by the other gives the direct gallon per millisecond-to-fluid ounce per millisecond factor of 128.
Simple example
1 gal/ms × 128 = 128 fl oz/ms
1 gallon per millisecond = 128 fluid ounces per millisecond.
Real-world example
60 gal/ms × 128 = 7,680 fl oz/ms
60 gallons per millisecond = 7,680 fluid ounces per millisecond.

Frequently asked questions
How many fluid ounces per millisecond are in 1 gallon per millisecond?
1 gallon per millisecond equals 128 fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to fluid ounce per millisecond?
Multiply the gallon per millisecond value by 128. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per millisecond back to gallon per millisecond?
Use the reverse factor: 1 fluid ounce per millisecond equals 0.0078125 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) is a unit of flow rate.
Is the gallon per millisecond to fluid ounce per millisecond conversion exact?
Yes. Both gallon per millisecond and fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 128 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.
