About Converting Gallon per Days to Cups per Fortnight
Gallon per Days 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 days × 224
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 cup per fortnight equals 1.955921e-10 base units, so dividing one by the other gives the direct gallon per days-to-cup per fortnight factor of 224.
Simple example
1 gal/d × 224 = 224 cup/fn
1 gallon per days = 224 cups per fortnight.
Real-world example
60 gal/d × 224 = 13,440 cup/fn
60 gallon per days = 13,440 cups per fortnight.

Frequently asked questions
How many cups per fortnight are in 1 gallon per days?
1 gallon per days equals 224 cups per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cup per fortnight?
Multiply the gallon per days value by 224. The converter above does this instantly to whatever precision you set.
How do I convert cup per fortnight back to gallon per days?
Use the reverse factor: 1 cup per fortnight equals 0.0044642857 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 cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
Is the gallon per days to cup per fortnight conversion exact?
Yes. Both gallon per days and cup per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 224 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.
