About Converting Cubic inches per Fortnight to Cup per Weeks
Cubic inch per Fortnight and Cup per Weeks 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
cup per weeks = cubic inches per fortnight × 0.034632034632
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per fortnight equals 1.354751e-11 base units, and 1 cup per weeks equals 3.911843e-10 base units, so dividing one by the other gives the direct cubic inch per fortnight-to-cup per weeks factor of 0.034632034632.
Simple example
1 in3/fn × 0.03463203463 = 0.0346320346 cup/wk
1 cubic inch per fortnight = 0.0346320346 cup per weeks.
Real-world example
60 in3/fn × 0.03463203463 = 2.077922078 cup/wk
60 cubic inches per fortnight = 2.077922078 cup per weeks.

What is a cubic inch per fortnight?
Cubic inch per Fortnight (in3/fn) is a unit of flow rate.
What is a cup per weeks?
Cup per Weeks (cup/wk) is a unit of flow rate.
Is the cubic inch per fortnight to cup per weeks conversion exact?
Yes. Both cubic inch per fortnight and cup per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.03463203463 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.
