About Converting Fluid ounces per Millisecond to Gallons per Millisecond
Fluid ounce per Millisecond and Gallon 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
gallons per millisecond = fluid ounces per millisecond × 0.0078125
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct fluid ounce per millisecond-to-gallon per millisecond factor of 0.0078125.
Simple example
1 fl oz/ms × 0.0078125 = 0.0078125 gal/ms
1 fluid ounce per millisecond = 0.0078125 gallons per millisecond.
Real-world example
60 fl oz/ms × 0.0078125 = 0.46875 gal/ms
60 fluid ounces per millisecond = 0.46875 gallons per millisecond.

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