About Converting Gallon per Hours to Cubic inches per Fortnight
Gallon per Hours and Cubic inch 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
cubic inches per fortnight = gallon per hours × 77616
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 cubic inch per fortnight equals 1.354751e-11 base units, so dividing one by the other gives the direct gallon per hours-to-cubic inch per fortnight factor of 77616.
Simple example
1 gal/h × 77616 = 77,616 in3/fn
1 gallon per hours = 77,616 cubic inches per fortnight.
Real-world example
60 gal/h × 77616 = 4,656,960 in3/fn
60 gallon per hours = 4,656,960 cubic inches per fortnight.

Frequently asked questions
How many cubic inches per fortnight are in 1 gallon per hours?
1 gallon per hours equals 77,616 cubic inches per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to cubic inch per fortnight?
Multiply the gallon per hours value by 77616. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per fortnight back to gallon per hours?
Use the reverse factor: 1 cubic inch per fortnight equals 0.0000128839 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a cubic inch per fortnight?
Cubic inch per Fortnight (in3/fn) is a unit of flow rate.
Is the gallon per hours to cubic inch per fortnight conversion exact?
Yes. Both gallon per hours and cubic inch per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 77616 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.
