About Converting Imperial gallons per Fortnight to Cubic inch per Days
Imperial gallon 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 = imperial gallons per fortnight × 19.8156737708
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 days equals 1.896651e-10 base units, so dividing one by the other gives the direct imperial gallon per fortnight-to-cubic inch per days factor of 19.8156737708.
Simple example
1 imp gal/fn × 19.81567377 = 19.81567377 in3/d
1 imperial gallon per fortnight = 19.81567377 cubic inch per days.
Real-world example
60 imp gal/fn × 19.81567377 = 1,188.940426 in3/d
60 imperial gallons per fortnight = 1,188.940426 cubic inch per days.

What is a imperial gallon per fortnight?
Imperial gallon per Fortnight (imp gal/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 imperial gallon per fortnight to cubic inch per days conversion exact?
Yes. Both imperial gallon per fortnight and cubic inch per days are defined by fixed standards rather than physical artifacts, so the factor of 19.81567377 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.
