About Converting Cup per Hours to Gallons per Fortnight
Cup per Hours 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 = cup per hours × 21
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct cup per hours-to-gallon per fortnight factor of 21.
Simple example
1 cup/h × 21 = 21 gal/fn
1 cup per hours = 21 gallons per fortnight.
Real-world example
60 cup/h × 21 = 1,260 gal/fn
60 cup per hours = 1,260 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 cup per hours?
1 cup per hours equals 21 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to gallon per fortnight?
Multiply the cup per hours value by 21. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to cup per hours?
Use the reverse factor: 1 gallon per fortnight equals 0.0476190476 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/h) 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 cup per hours to gallon per fortnight conversion exact?
Yes. Both cup per hours and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 21 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.
