About Converting Gallons per Fortnight to Imperial gallon per Weeks
Gallon per Fortnight and Imperial gallon per Weeks 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 weeks = gallons per fortnight × 0.416337092314
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per fortnight equals 3.129474e-9 base units, and 1 imperial gallon per weeks equals 7.516683e-9 base units, so dividing one by the other gives the direct gallon per fortnight-to-imperial gallon per weeks factor of 0.416337092314.

What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
What is a imperial gallon per weeks?
Imperial gallon per Weeks (imp gal/wk) is a unit of flow rate.
Is the gallon per fortnight to imperial gallon per weeks conversion exact?
Yes. Both gallon per fortnight and imperial gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.4163370923 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.
