About Converting Quart per Seconds to Cubic feet per Fortnight
Quart 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. Both are volumetric flow rate units.
Formula
cubic feet per fortnight = quart per seconds × 40425
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 cubic foot per fortnight equals 2.341009e-8 base units, so dividing one by the other gives the direct quart per seconds-to-cubic foot per fortnight factor of 40425.
Simple example
1 qt/s × 40425 = 40,425 ft3/fn
1 quart per seconds = 40,425 cubic feet per fortnight.
Real-world example
60 qt/s × 40425 = 2,425,500 ft3/fn
60 quart per seconds = 2,425,500 cubic feet per fortnight.

Frequently asked questions
How many cubic feet per fortnight are in 1 quart per seconds?
1 quart per seconds equals 40,425 cubic feet per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to cubic foot per fortnight?
Multiply the quart per seconds value by 40425. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per fortnight back to quart per seconds?
Use the reverse factor: 1 cubic foot per fortnight equals 0.0000247372 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
Is the quart per seconds to cubic foot per fortnight conversion exact?
Yes. Both quart per seconds and cubic foot per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 40425 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.
