About Converting Imperial gallon per Seconds to Gallons per Fortnight
Imperial gallon per Seconds 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. Both are volumetric flow rate units.
Formula
gallons per fortnight = imperial gallon per seconds × 1452669.02989
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-gallon per fortnight factor of 1452669.02989.
Simple example
1 imp gal/s × 1452669.03 = 1,452,669.03 gal/fn
1 imperial gallon per seconds = 1,452,669.03 gallons per fortnight.
Real-world example
60 imp gal/s × 1452669.03 = 87,160,141.79 gal/fn
60 imperial gallon per seconds = 87,160,141.79 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 1,452,669.03 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to gallon per fortnight?
Multiply the imperial gallon per seconds value by 1452669.03. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to imperial gallon per seconds?
Use the reverse factor: 1 gallon per fortnight equals 6.88388e-7 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the imperial gallon per seconds to gallon per fortnight conversion exact?
Yes. Both imperial gallon per seconds and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 1452669.03 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.
