About Converting Gallon per Seconds to Cubic Kilometers per Fortnight
Gallon per Seconds and Cubic Kilometer 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 kilometers per fortnight = gallon per seconds × 0.00000457883409393
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 kilometer per fortnight equals 826.71957672 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic kilometer per fortnight factor of 0.00000457883409393.
Simple example
1 gal/s × 0.000004578834094 = 0.0000045788 km3/fn
1 gallon per seconds = 0.0000045788 cubic kilometers per fortnight.
Real-world example
60 gal/s × 0.000004578834094 = 0.00027473 km3/fn
60 gallon per seconds = 0.00027473 cubic kilometers per fortnight.

Frequently asked questions
How many cubic kilometers per fortnight are in 1 gallon per seconds?
1 gallon per seconds equals 0.0000045788 cubic kilometers per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic kilometer per fortnight?
Multiply the gallon per seconds value by 0.000004578834094. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per fortnight back to gallon per seconds?
Use the reverse factor: 1 cubic kilometer per fortnight equals 218,396.2073 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 kilometer per fortnight?
Cubic Kilometer per Fortnight (km3/fn) is a unit of flow rate.
Is the gallon per seconds to cubic kilometer per fortnight conversion exact?
Yes. Both gallon per seconds and cubic kilometer per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.000004578834094 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.
