About Converting Cubic foot per Seconds to Imperial fluid ounces per Millisecond
Cubic foot per Seconds 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
imperial fluid ounces per millisecond = cubic foot per seconds × 0.996613673447
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 imperial fluid ounce per millisecond equals 0.0284130625 base units, so dividing one by the other gives the direct cubic foot per seconds-to-imperial fluid ounce per millisecond factor of 0.996613673447.
Simple example
1 ft3/s × 0.9966136734 = 0.9966136734 imp fl oz/ms
1 cubic foot per seconds = 0.9966136734 imperial fluid ounces per millisecond.
Real-world example
60 ft3/s × 0.9966136734 = 59.79682041 imp fl oz/ms
60 cubic foot per seconds = 59.79682041 imperial fluid ounces per millisecond.

Frequently asked questions
How many imperial fluid ounces per millisecond are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 0.9966136734 imperial fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to imperial fluid ounce per millisecond?
Multiply the cubic foot per seconds value by 0.9966136734. The converter above does this instantly to whatever precision you set.
How do I convert imperial fluid ounce per millisecond back to cubic foot per seconds?
Use the reverse factor: 1 imperial fluid ounce per millisecond equals 1.003397833 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
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 cubic foot per seconds to imperial fluid ounce per millisecond conversion exact?
Yes. Both cubic foot per seconds and imperial fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.9966136734 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
