About Converting Cubic Meter per Seconds to Cubic feet per Fortnight
Cubic Meter per Seconds and Cubic foot 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. Cubic Meter per Seconds is most often used for used by hydrologists and water-resource engineers internationally to report river and reservoir discharge at large scales.
Formula
cubic feet per fortnight = cubic meter per seconds × 42716620.8663
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per seconds equals 1 base unit, and 1 cubic foot per fortnight equals 2.341009e-8 base units, so dividing one by the other gives the direct cubic meter per seconds-to-cubic foot per fortnight factor of 42716620.8663.
Simple example
1 m3/s × 42716620.87 = 42,716,620.87 ft3/fn
1 cubic meter per seconds = 42,716,620.87 cubic feet per fortnight.
Real-world example
60 m3/s × 42716620.87 = 2,562,997,252 ft3/fn
60 cubic meter per seconds = 2,562,997,252 cubic feet per fortnight.

Frequently asked questions
How many cubic feet per fortnight are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 42,716,620.87 cubic feet per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to cubic foot per fortnight?
Multiply the cubic meter per seconds value by 42716620.87. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per fortnight back to cubic meter per seconds?
Use the reverse factor: 1 cubic foot per fortnight equals 2.341009e-8 cubic meter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
Is the cubic meter per seconds to cubic foot per fortnight conversion exact?
Yes. Both cubic meter per seconds and cubic foot per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 42716620.87 used above is exact to as many digits as you choose to display.
Where is the cubic meter per seconds still used today?
Used internationally in hydrology and large-scale water-resource engineering
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.
