About Converting Gallons per Fortnight to Cup per Days
Gallon per Fortnight and Cup per Days 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
cup per days = gallons per fortnight × 1.14285714286
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct gallon per fortnight-to-cup per days factor of 1.14285714286.
Simple example
1 gal/fn × 1.142857143 = 1.142857143 cup/d
1 gallon per fortnight = 1.142857143 cup per days.
Real-world example
60 gal/fn × 1.142857143 = 68.57142857 cup/d
60 gallons per fortnight = 68.57142857 cup per days.

Frequently asked questions
How many cup per days are in 1 gallon per fortnight?
1 gallon per fortnight equals 1.142857143 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per fortnight to cup per days?
Multiply the gallon per fortnight value by 1.142857143. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to gallon per fortnight?
Use the reverse factor: 1 cup per days equals 0.875 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 cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the gallon per fortnight to cup per days conversion exact?
Yes. Both gallon per fortnight and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 1.142857143 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.
