About Converting Cubic feet per Fortnight to Gallon per Seconds
Cubic foot per Fortnight and Gallon 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. Both are volumetric flow rate units.
Formula
gallon per seconds = cubic feet per fortnight × 0.00000618429189858
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per fortnight equals 2.341009e-8 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic foot per fortnight-to-gallon per seconds factor of 0.00000618429189858.
Simple example
1 ft3/fn × 0.000006184291899 = 0.0000061843 gal/s
1 cubic foot per fortnight = 0.0000061843 gallon per seconds.
Real-world example
60 ft3/fn × 0.000006184291899 = 0.0003710575 gal/s
60 cubic feet per fortnight = 0.0003710575 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic foot per fortnight?
1 cubic foot per fortnight equals 0.0000061843 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per fortnight to gallon per seconds?
Multiply the cubic foot per fortnight value by 0.000006184291899. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic foot per fortnight?
Use the reverse factor: 1 gallon per seconds equals 161,700 cubic feet per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic foot per fortnight to gallon per seconds conversion exact?
Yes. Both cubic foot per fortnight and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000006184291899 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.
