About Converting Gallon per Days to Cubic feet per Fortnight
Gallon per Days and Cubic foot 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. Both are volumetric flow rate units.
Formula
cubic feet per fortnight = gallon per days × 1.87152777778
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 cubic foot per fortnight equals 2.341009e-8 base units, so dividing one by the other gives the direct gallon per days-to-cubic foot per fortnight factor of 1.87152777778.
Simple example
1 gal/d × 1.871527778 = 1.871527778 ft3/fn
1 gallon per days = 1.871527778 cubic feet per fortnight.
Real-world example
60 gal/d × 1.871527778 = 112.2916667 ft3/fn
60 gallon per days = 112.2916667 cubic feet per fortnight.

Frequently asked questions
How many cubic feet per fortnight are in 1 gallon per days?
1 gallon per days equals 1.871527778 cubic feet per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cubic foot per fortnight?
Multiply the gallon per days value by 1.871527778. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per fortnight back to gallon per days?
Use the reverse factor: 1 cubic foot per fortnight equals 0.53432282 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
Is the gallon per days to cubic foot per fortnight conversion exact?
Yes. Both gallon per days and cubic foot per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 1.871527778 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.
