About Converting Cubic foot per Minutes to Imperial fluid ounce per Seconds
Cubic foot per Minutes and Imperial fluid ounce per Seconds 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 Minutes is most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
imperial fluid ounce per seconds = cubic foot per minutes × 16.6102278908
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 base units, and 1 imperial fluid ounce per seconds equals 0.0000284130625 base units, so dividing one by the other gives the direct cubic foot per minutes-to-imperial fluid ounce per seconds factor of 16.6102278908.
Simple example
1 ft3/min × 16.61022789 = 16.61022789 imp fl oz/s
1 cubic foot per minutes = 16.61022789 imperial fluid ounce per seconds.
Real-world example
60 ft3/min × 16.61022789 = 996.6136734 imp fl oz/s
60 cubic foot per minutes = 996.6136734 imperial fluid ounce per seconds.

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.
