About Converting Gallon per Days to Gallons per Fortnight
Gallon per Days and 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
gallons per fortnight = gallon per days × 14
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct gallon per days-to-gallon per fortnight factor of 14.
Simple example
1 gal/d × 14 = 14 gal/fn
1 gallon per days = 14 gallons per fortnight.
Real-world example
60 gal/d × 14 = 840 gal/fn
60 gallon per days = 840 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 gallon per days?
1 gallon per days equals 14 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to gallon per fortnight?
Multiply the gallon per days value by 14. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to gallon per days?
Use the reverse factor: 1 gallon per fortnight equals 0.0714285714 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the gallon per days to gallon per fortnight conversion exact?
Yes. Both gallon per days and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 14 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.
