About Converting Cubic foot per Seconds to Fluid ounces per Fortnight
Cubic foot per Seconds and Fluid ounce per Fortnight 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
fluid ounces per fortnight = cubic foot per seconds × 1158199854.55
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 fluid ounce per fortnight equals 2.444902e-11 base units, so dividing one by the other gives the direct cubic foot per seconds-to-fluid ounce per fortnight factor of 1158199854.55.
Simple example
1 ft3/s × 1158199855 = 1,158,199,855 fl oz/fn
1 cubic foot per seconds = 1,158,199,855 fluid ounces per fortnight.
Real-world example
60 ft3/s × 1158199855 = 69,491,991,270 fl oz/fn
60 cubic foot per seconds = 69,491,991,270 fluid ounces per fortnight.

Frequently asked questions
How many fluid ounces per fortnight are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 1,158,199,855 fluid ounces per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to fluid ounce per fortnight?
Multiply the cubic foot per seconds value by 1158199855. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per fortnight back to cubic foot per seconds?
Use the reverse factor: 1 fluid ounce per fortnight equals 8.634088e-10 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 fluid ounce per fortnight?
Fluid ounce per Fortnight (fl oz/fn) is a unit of flow rate.
Is the cubic foot per seconds to fluid ounce per fortnight conversion exact?
Yes. Both cubic foot per seconds and fluid ounce per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 1158199855 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.
