About Converting Imperial gallon per Minutes to Fluid ounces per Millisecond
Imperial gallon per Minutes 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 = imperial gallon per minutes × 0.00256202650774
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per minutes equals 0.0000757681666667 base units, and 1 fluid ounce per millisecond equals 0.0295735295625 base units, so dividing one by the other gives the direct imperial gallon per minutes-to-fluid ounce per millisecond factor of 0.00256202650774.
Simple example
1 imp gal/min × 0.002562026508 = 0.0025620265 fl oz/ms
1 imperial gallon per minutes = 0.0025620265 fluid ounces per millisecond.
Real-world example
60 imp gal/min × 0.002562026508 = 0.1537215905 fl oz/ms
60 imperial gallon per minutes = 0.1537215905 fluid ounces per millisecond.

Frequently asked questions
How many fluid ounces per millisecond are in 1 imperial gallon per minutes?
1 imperial gallon per minutes equals 0.0025620265 fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per minutes to fluid ounce per millisecond?
Multiply the imperial gallon per minutes value by 0.002562026508. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per millisecond back to imperial gallon per minutes?
Use the reverse factor: 1 fluid ounce per millisecond equals 390.316024 imperial gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) 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 imperial gallon per minutes to fluid ounce per millisecond conversion exact?
Yes. Both imperial gallon per minutes and fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.002562026508 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.
