About Converting Cubic feet per Fortnight to Gallon per Minutes
Cubic foot per Fortnight and Gallon per Minutes 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 minutes = cubic feet per fortnight × 0.000371057513915
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 minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct cubic foot per fortnight-to-gallon per minutes factor of 0.000371057513915.
Simple example
1 ft3/fn × 0.0003710575139 = 0.0003710575 gal/min
1 cubic foot per fortnight = 0.0003710575 gallon per minutes.
Real-world example
60 ft3/fn × 0.0003710575139 = 0.0222634508 gal/min
60 cubic feet per fortnight = 0.0222634508 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 cubic foot per fortnight?
1 cubic foot per fortnight equals 0.0003710575 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per fortnight to gallon per minutes?
Multiply the cubic foot per fortnight value by 0.0003710575139. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to cubic foot per fortnight?
Use the reverse factor: 1 gallon per minutes equals 2,695 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 minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the cubic foot per fortnight to gallon per minutes conversion exact?
Yes. Both cubic foot per fortnight and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0003710575139 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.
