About Converting Imperial gallons per Fortnight to Cubic inch per Weeks
Imperial gallon per Fortnight and Cubic inch 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
cubic inch per weeks = imperial gallons per fortnight × 138.709716396
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per fortnight equals 3.758342e-9 base units, and 1 cubic inch per weeks equals 2.709501e-11 base units, so dividing one by the other gives the direct imperial gallon per fortnight-to-cubic inch per weeks factor of 138.709716396.

What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) is a unit of flow rate.
Is the imperial gallon per fortnight to cubic inch per weeks conversion exact?
Yes. Both imperial gallon per fortnight and cubic inch per weeks are defined by fixed standards rather than physical artifacts, so the factor of 138.7097164 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.
