About Converting Cup per Days to Quarts per Fortnight
Cup per Days and Quart 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
quarts per fortnight = cup per days × 3.5
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 quart per fortnight equals 7.823685e-10 base units, so dividing one by the other gives the direct cup per days-to-quart per fortnight factor of 3.5.
Simple example
1 cup/d × 3.5 = 3.5 qt/fn
1 cup per days = 3.5 quarts per fortnight.
Real-world example
60 cup/d × 3.5 = 210 qt/fn
60 cup per days = 210 quarts per fortnight.

Frequently asked questions
How many quarts per fortnight are in 1 cup per days?
1 cup per days equals 3.5 quarts per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to quart per fortnight?
Multiply the cup per days value by 3.5. The converter above does this instantly to whatever precision you set.
How do I convert quart per fortnight back to cup per days?
Use the reverse factor: 1 quart per fortnight equals 0.2857142857 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a quart per fortnight?
Quart per Fortnight (qt/fn) is a unit of flow rate.
Is the cup per days to quart per fortnight conversion exact?
Yes. Both cup per days and quart per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 3.5 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.
