About Converting Gallons per Fortnight to Cubic foot per Years
Gallon per Fortnight and Cubic foot per Years 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
cubic foot per years = gallons per fortnight × 3.48755859375
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per fortnight equals 3.129474e-9 base units, and 1 cubic foot per years equals 8.973251e-10 base units, so dividing one by the other gives the direct gallon per fortnight-to-cubic foot per years factor of 3.48755859375.
Simple example
1 gal/fn × 3.487558594 = 3.487558594 ft3/yr
1 gallon per fortnight = 3.487558594 cubic foot per years.
Real-world example
60 gal/fn × 3.487558594 = 209.2535156 ft3/yr
60 gallons per fortnight = 209.2535156 cubic foot per years.

Frequently asked questions
How many cubic foot per years are in 1 gallon per fortnight?
1 gallon per fortnight equals 3.487558594 cubic foot per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per fortnight to cubic foot per years?
Multiply the gallon per fortnight value by 3.487558594. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per years back to gallon per fortnight?
Use the reverse factor: 1 cubic foot per years equals 0.2867335338 gallons per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
What is a cubic foot per years?
Cubic foot per Years (ft3/yr) is a unit of flow rate.
Is the gallon per fortnight to cubic foot per years conversion exact?
Yes. Both gallon per fortnight and cubic foot per years are defined by fixed standards rather than physical artifacts, so the factor of 3.487558594 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.
