About Converting Cups per Fortnight to Imperial gallon per Seconds
Cup per Fortnight and Imperial gallon 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
imperial gallon per seconds = cups per fortnight × 4.302425e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per fortnight equals 1.955921e-10 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cup per fortnight-to-imperial gallon per seconds factor of 4.302425e-8.
Simple example
1 cup/fn × 4.302425e-8 = 4.302425e-8 imp gal/s
1 cup per fortnight = 4.302425e-8 imperial gallon per seconds.
Real-world example
60 cup/fn × 4.302425e-8 = 0.0000025815 imp gal/s
60 cups per fortnight = 0.0000025815 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cup per fortnight?
1 cup per fortnight equals 4.302425e-8 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per fortnight to imperial gallon per seconds?
Multiply the cup per fortnight value by 4.302425e-8. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cup per fortnight?
Use the reverse factor: 1 imperial gallon per seconds equals 23,242,704.48 cups per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cup per fortnight to imperial gallon per seconds conversion exact?
Yes. Both cup per fortnight and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4.302425e-8 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.
