About Converting Gallons per Fortnight to Liters per Millisecond
Gallon per Fortnight and Liter per Millisecond 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 millisecond = gallons per fortnight × 3.129474e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per fortnight equals 3.129474e-9 base units, and 1 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct gallon per fortnight-to-liter per millisecond factor of 3.129474e-9.
Simple example
1 gal/fn × 3.129474e-9 = 3.129474e-9 L/ms
1 gallon per fortnight = 3.129474e-9 liters per millisecond.
Real-world example
60 gal/fn × 3.129474e-9 = 1.877684e-7 L/ms
60 gallons per fortnight = 1.877684e-7 liters per millisecond.

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