About Converting Liters per Millisecond to Gallons per Fortnight
Liter per Millisecond 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 = liters per millisecond × 319542514.532
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct liter per millisecond-to-gallon per fortnight factor of 319542514.532.
Simple example
1 L/ms × 319542514.5 = 319,542,514.5 gal/fn
1 liter per millisecond = 319,542,514.5 gallons per fortnight.
Real-world example
60 L/ms × 319542514.5 = 19,172,550,870 gal/fn
60 liters per millisecond = 19,172,550,870 gallons per fortnight.

Reverse conversion: Gallon per Fortnight to Liter per Millisecond
1 gal/fn × 3.129474e-9 = 3.129474e-9 L/ms
1 gallon per fortnight = 3.129474e-9 liters per millisecond.
liters per millisecond = gallons per fortnight × 3.129474e-9

Frequently asked questions
How many gallons per fortnight are in 1 liter per millisecond?
1 liter per millisecond equals 319,542,514.5 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to gallon per fortnight?
Multiply the liter per millisecond value by 319542514.5. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to liter per millisecond?
Use the reverse factor: 1 gallon per fortnight equals 3.129474e-9 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) 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 liter per millisecond to gallon per fortnight conversion exact?
Yes. Both liter per millisecond and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 319542514.5 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.
