About Converting Cups per Fortnight to Cubic inch per Days
Cup per Fortnight and Cubic inch 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
cubic inch per days = cups per fortnight × 1.03125
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per fortnight equals 1.955921e-10 base units, and 1 cubic inch per days equals 1.896651e-10 base units, so dividing one by the other gives the direct cup per fortnight-to-cubic inch per days factor of 1.03125.
Simple example
1 cup/fn × 1.03125 = 1.03125 in3/d
1 cup per fortnight = 1.03125 cubic inch per days.
Real-world example
60 cup/fn × 1.03125 = 61.875 in3/d
60 cups per fortnight = 61.875 cubic inch per days.

Frequently asked questions
How many cubic inch per days are in 1 cup per fortnight?
1 cup per fortnight equals 1.03125 cubic inch per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per fortnight to cubic inch per days?
Multiply the cup per fortnight value by 1.03125. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per days back to cup per fortnight?
Use the reverse factor: 1 cubic inch per days equals 0.9696969697 cups per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per fortnight?
Cup per Fortnight (cup/fn) is a unit of flow rate.
What is a cubic inch per days?
Cubic inch per Days (in3/d) is a unit of flow rate.
Is the cup per fortnight to cubic inch per days conversion exact?
Yes. Both cup per fortnight and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 1.03125 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.
