About Converting Gallon per Seconds to Liters per Fortnight
Gallon per Seconds and Liter 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
liters per fortnight = gallon per seconds × 4578834.09393
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 liter per fortnight equals 8.267196e-10 base units, so dividing one by the other gives the direct gallon per seconds-to-liter per fortnight factor of 4578834.09393.
Simple example
1 gal/s × 4578834.094 = 4,578,834.094 L/fn
1 gallon per seconds = 4,578,834.094 liters per fortnight.
Real-world example
60 gal/s × 4578834.094 = 274,730,045.6 L/fn
60 gallon per seconds = 274,730,045.6 liters per fortnight.

Reverse conversion: Liter per Fortnight to Gallon per Seconds
1 L/fn × 2.183962e-7 = 2.183962e-7 gal/s
1 liter per fortnight = 2.183962e-7 gallon per seconds.
gallon per seconds = liters per fortnight × 2.183962e-7

Frequently asked questions
How many liters per fortnight are in 1 gallon per seconds?
1 gallon per seconds equals 4,578,834.094 liters per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to liter per fortnight?
Multiply the gallon per seconds value by 4578834.094. The converter above does this instantly to whatever precision you set.
How do I convert liter per fortnight back to gallon per seconds?
Use the reverse factor: 1 liter per fortnight equals 2.183962e-7 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a liter per fortnight?
Liter per Fortnight (L/fn) is a unit of flow rate.
Is the gallon per seconds to liter per fortnight conversion exact?
Yes. Both gallon per seconds and liter per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 4578834.094 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.
