About Converting Cubic inches per Fortnight to Imperial gallon per Days
Cubic inch per Fortnight and Imperial gallon 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
imperial gallon per days = cubic inches per fortnight × 0.000257475010708
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 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct cubic inch per fortnight-to-imperial gallon per days factor of 0.000257475010708.
Simple example
1 in3/fn × 0.0002574750107 = 0.000257475 imp gal/d
1 cubic inch per fortnight = 0.000257475 imperial gallon per days.
Real-world example
60 in3/fn × 0.0002574750107 = 0.0154485006 imp gal/d
60 cubic inches per fortnight = 0.0154485006 imperial gallon per days.

Frequently asked questions
How many imperial gallon per days are in 1 cubic inch per fortnight?
1 cubic inch per fortnight equals 0.000257475 imperial gallon per days, using the exact defined conversion factor rather than an estimate.

Multiply the cubic inch per fortnight value by 0.0002574750107. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per days back to cubic inch per fortnight?
Use the reverse factor: 1 imperial gallon per days equals 3,883.872059 cubic inches per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per fortnight?
Cubic inch per Fortnight (in3/fn) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the cubic inch per fortnight to imperial gallon per days conversion exact?
Yes. Both cubic inch per fortnight and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0002574750107 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.
