About Converting Gallon per Minutes to Liters per Fortnight
Gallon per Minutes 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
liters per fortnight = gallon per minutes × 76313.9015654
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 liter per fortnight equals 8.267196e-10 base units, so dividing one by the other gives the direct gallon per minutes-to-liter per fortnight factor of 76313.9015654.
Simple example
1 gal/min × 76313.90157 = 76,313.90157 L/fn
1 gallon per minutes = 76,313.90157 liters per fortnight.
Real-world example
60 gal/min × 76313.90157 = 4,578,834.094 L/fn
60 gallon per minutes = 4,578,834.094 liters per fortnight.

Frequently asked questions
How many liters per fortnight are in 1 gallon per minutes?
1 gallon per minutes equals 76,313.90157 liters per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to liter per fortnight?
Multiply the gallon per minutes value by 76313.90157. The converter above does this instantly to whatever precision you set.
How do I convert liter per fortnight back to gallon per minutes?
Use the reverse factor: 1 liter per fortnight equals 0.0000131038 gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a liter per fortnight?
Liter per Fortnight (L/fn) is a unit of flow rate.
Is the gallon per minutes to liter per fortnight conversion exact?
Yes. Both gallon per minutes and liter per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 76313.90157 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
