About Converting Gallon per Years to Cups per Fortnight
Gallon per Years and Cup 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
cups per fortnight = gallon per years × 0.613291169565
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 cup per fortnight equals 1.955921e-10 base units, so dividing one by the other gives the direct gallon per years-to-cup per fortnight factor of 0.613291169565.
Simple example
1 gal/yr × 0.6132911696 = 0.6132911696 cup/fn
1 gallon per years = 0.6132911696 cups per fortnight.
Real-world example
60 gal/yr × 0.6132911696 = 36.79747017 cup/fn
60 gallon per years = 36.79747017 cups per fortnight.

Frequently asked questions
How many cups per fortnight are in 1 gallon per years?
1 gallon per years equals 0.6132911696 cups per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to cup per fortnight?
Multiply the gallon per years value by 0.6132911696. The converter above does this instantly to whatever precision you set.
How do I convert cup per fortnight back to gallon per years?
Use the reverse factor: 1 cup per fortnight equals 1.630546875 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
Is the gallon per years to cup per fortnight conversion exact?
Yes. Both gallon per years and cup per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.6132911696 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.
