About Converting Cubic inches per Fortnight to Gallons per Fortnight
Cubic inch per Fortnight and Gallon 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
gallons per fortnight = cubic inches per fortnight × 0.004329004329
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 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct cubic inch per fortnight-to-gallon per fortnight factor of 0.004329004329.
Simple example
1 in3/fn × 0.004329004329 = 0.0043290043 gal/fn
1 cubic inch per fortnight = 0.0043290043 gallons per fortnight.
Real-world example
60 in3/fn × 0.004329004329 = 0.2597402597 gal/fn
60 cubic inches per fortnight = 0.2597402597 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 cubic inch per fortnight?
1 cubic inch per fortnight equals 0.0043290043 gallons per fortnight, using the exact defined conversion factor rather than an estimate.

How do I convert gallon per fortnight back to cubic inch per fortnight?
Use the reverse factor: 1 gallon per fortnight equals 231 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 gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the cubic inch per fortnight to gallon per fortnight conversion exact?
Yes. Both cubic inch per fortnight and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.004329004329 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.
