About Converting Cubic foot per Minutes to Gallons per Fortnight
Cubic foot per Minutes and Gallon 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 Minutes is most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
gallons per fortnight = cubic foot per minutes × 150807.272727
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct cubic foot per minutes-to-gallon per fortnight factor of 150807.272727.
Simple example
1 ft3/min × 150807.2727 = 150,807.2727 gal/fn
1 cubic foot per minutes = 150,807.2727 gallons per fortnight.
Real-world example
60 ft3/min × 150807.2727 = 9,048,436.364 gal/fn
60 cubic foot per minutes = 9,048,436.364 gallons per fortnight.

United States, and widely recognized internationally in HVAC and compressed-air equipment specifications
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.
