About Converting Gallon per Hours to Imperial gallons per Fortnight
Gallon per Hours and Imperial gallon 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
imperial gallons per fortnight = gallon per hours × 279.778526035
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 imperial gallon per fortnight equals 3.758342e-9 base units, so dividing one by the other gives the direct gallon per hours-to-imperial gallon per fortnight factor of 279.778526035.
Simple example
1 gal/h × 279.778526 = 279.778526 imp gal/fn
1 gallon per hours = 279.778526 imperial gallons per fortnight.
Real-world example
60 gal/h × 279.778526 = 16,786.71156 imp gal/fn
60 gallon per hours = 16,786.71156 imperial gallons per fortnight.

Frequently asked questions
How many imperial gallons per fortnight are in 1 gallon per hours?
1 gallon per hours equals 279.778526 imperial gallons per fortnight, using the exact defined conversion factor rather than an estimate.

Multiply the gallon per hours value by 279.778526. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per fortnight back to gallon per hours?
Use the reverse factor: 1 imperial gallon per fortnight equals 0.0035742557 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a imperial gallon per fortnight?
Imperial gallon per Fortnight (imp gal/fn) is a unit of flow rate.
Is the gallon per hours to imperial gallon per fortnight conversion exact?
Yes. Both gallon per hours and imperial gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 279.778526 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.
