About Converting Cubic feet per Fortnight to Cubic Kilometer per Seconds
Cubic foot per Fortnight and Cubic Kilometer per Seconds 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 kilometer per seconds = cubic feet per fortnight × 2.341009e-17
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per fortnight equals 2.341009e-8 base units, and 1 cubic kilometer per seconds equals 1000000000 base units, so dividing one by the other gives the direct cubic foot per fortnight-to-cubic kilometer per seconds factor of 2.341009e-17.
Simple example
1 ft3/fn × 2.341009e-17 = 2.341009e-17 km3/s
1 cubic foot per fortnight = 2.341009e-17 cubic kilometer per seconds.
Real-world example
60 ft3/fn × 2.341009e-17 = 1.404605e-15 km3/s
60 cubic feet per fortnight = 1.404605e-15 cubic kilometer per seconds.

Frequently asked questions
How many cubic kilometer per seconds are in 1 cubic foot per fortnight?
1 cubic foot per fortnight equals 2.341009e-17 cubic kilometer per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per fortnight to cubic kilometer per seconds?
Multiply the cubic foot per fortnight value by 2.341009e-17. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per seconds back to cubic foot per fortnight?
Use the reverse factor: 1 cubic kilometer per seconds equals 4.271662e+16 cubic feet per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
What is a cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
Is the cubic foot per fortnight to cubic kilometer per seconds conversion exact?
Yes. Both cubic foot per fortnight and cubic kilometer per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.341009e-17 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.
