About Converting Cubic inches per Fortnight to Gallon per Hours
Cubic inch per Fortnight and Gallon per Hours 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
gallon per hours = cubic inches per fortnight × 0.0000128839414554
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 hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic inch per fortnight-to-gallon per hours factor of 0.0000128839414554.
Simple example
1 in3/fn × 0.00001288394146 = 0.0000128839 gal/h
1 cubic inch per fortnight = 0.0000128839 gallon per hours.
Real-world example
60 in3/fn × 0.00001288394146 = 0.0007730365 gal/h
60 cubic inches per fortnight = 0.0007730365 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 cubic inch per fortnight?
1 cubic inch per fortnight equals 0.0000128839 gallon per hours, using the exact defined conversion factor rather than an estimate.

Multiply the cubic inch per fortnight value by 0.00001288394146. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic inch per fortnight?
Use the reverse factor: 1 gallon per hours equals 77,616 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 hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic inch per fortnight to gallon per hours conversion exact?
Yes. Both cubic inch per fortnight and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.00001288394146 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.
