About Converting Gallon per Seconds to Cubic Meters per Fortnight
Gallon per Seconds and Cubic Meter 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
cubic meters per fortnight = gallon per seconds × 4578.83409393
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 cubic meter per fortnight equals 8.267196e-7 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic meter per fortnight factor of 4578.83409393.
Simple example
1 gal/s × 4578.834094 = 4,578.834094 m3/fn
1 gallon per seconds = 4,578.834094 cubic meters per fortnight.
Real-world example
60 gal/s × 4578.834094 = 274,730.0456 m3/fn
60 gallon per seconds = 274,730.0456 cubic meters per fortnight.

Frequently asked questions
How many cubic meters per fortnight are in 1 gallon per seconds?
1 gallon per seconds equals 4,578.834094 cubic meters per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic meter per fortnight?
Multiply the gallon per seconds value by 4578.834094. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per fortnight back to gallon per seconds?
Use the reverse factor: 1 cubic meter per fortnight equals 0.0002183962 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 cubic meter per fortnight?
Cubic Meter per Fortnight (m3/fn) is a unit of flow rate.
Is the gallon per seconds to cubic meter per fortnight conversion exact?
Yes. Both gallon per seconds and cubic meter per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 4578.834094 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.
