About Converting Gallons per Fortnight to Gallon per Weeks
Gallon per Fortnight and 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
gallon per weeks = gallons per fortnight × 0.5
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 gallon per weeks equals 6.258948e-9 base units, so dividing one by the other gives the direct gallon per fortnight-to-gallon per weeks factor of 0.5.
Simple example
1 gal/fn × 0.5 = 0.5 gal/wk
1 gallon per fortnight = 0.5 gallon per weeks.
Real-world example
60 gal/fn × 0.5 = 30 gal/wk
60 gallons per fortnight = 30 gallon per weeks.

Frequently asked questions
How many gallon per weeks are in 1 gallon per fortnight?
1 gallon per fortnight equals 0.5 gallon per weeks, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per fortnight to gallon per weeks?
Multiply the gallon per fortnight value by 0.5. The converter above does this instantly to whatever precision you set.
How do I convert gallon per weeks back to gallon per fortnight?
Use the reverse factor: 1 gallon per weeks equals 2 gallons per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
Is the gallon per fortnight to gallon per weeks conversion exact?
Yes. Both gallon per fortnight and gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.5 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.
