About Converting Cubic inch per Weeks to Cups per Fortnight
Cubic inch per Weeks 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 = cubic inch per weeks × 0.138528138528
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per weeks equals 2.709501e-11 base units, and 1 cup per fortnight equals 1.955921e-10 base units, so dividing one by the other gives the direct cubic inch per weeks-to-cup per fortnight factor of 0.138528138528.
Simple example
1 in3/wk × 0.1385281385 = 0.1385281385 cup/fn
1 cubic inch per weeks = 0.1385281385 cups per fortnight.
Real-world example
60 in3/wk × 0.1385281385 = 8.311688312 cup/fn
60 cubic inch per weeks = 8.311688312 cups per fortnight.

Frequently asked questions
How many cups per fortnight are in 1 cubic inch per weeks?
1 cubic inch per weeks equals 0.1385281385 cups per fortnight, using the exact defined conversion factor rather than an estimate.

How do I convert cup per fortnight back to cubic inch per weeks?
Use the reverse factor: 1 cup per fortnight equals 7.21875 cubic inch per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) 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 cubic inch per weeks to cup per fortnight conversion exact?
Yes. Both cubic inch per weeks and cup per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.1385281385 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.
