About Converting Gallons per Fortnight to Imperial gallon per Years
Gallon per Fortnight and Imperial gallon per Years 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 years = gallons per fortnight × 21.7234286342
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 years equals 1.440599e-10 base units, so dividing one by the other gives the direct gallon per fortnight-to-imperial gallon per years factor of 21.7234286342.
Simple example
1 gal/fn × 21.72342863 = 21.72342863 imp gal/yr
1 gallon per fortnight = 21.72342863 imperial gallon per years.
Real-world example
60 gal/fn × 21.72342863 = 1,303.405718 imp gal/yr
60 gallons per fortnight = 1,303.405718 imperial gallon per years.

Frequently asked questions
How many imperial gallon per years are in 1 gallon per fortnight?
1 gallon per fortnight equals 21.72342863 imperial gallon per years, using the exact defined conversion factor rather than an estimate.

What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) is a unit of flow rate.
Is the gallon per fortnight to imperial gallon per years conversion exact?
Yes. Both gallon per fortnight and imperial gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 21.72342863 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.
