About Converting Liters per Fortnight to Gallon per Seconds
Liter per Fortnight and Gallon per Seconds 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
gallon per seconds = liters per fortnight × 2.183962e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per fortnight equals 8.267196e-10 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct liter per fortnight-to-gallon per seconds factor of 2.183962e-7.
Simple example
1 L/fn × 2.183962e-7 = 2.183962e-7 gal/s
1 liter per fortnight = 2.183962e-7 gallon per seconds.
Real-world example
60 L/fn × 2.183962e-7 = 0.0000131038 gal/s
60 liters per fortnight = 0.0000131038 gallon per seconds.

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