About Converting Cubic inch per Years to Gallons per Fortnight
Cubic inch per Years 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 inch per years × 0.000165933757999
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per years equals 5.192854e-13 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 years-to-gallon per fortnight factor of 0.000165933757999.
Simple example
1 in3/yr × 0.000165933758 = 0.0001659338 gal/fn
1 cubic inch per years = 0.0001659338 gallons per fortnight.
Real-world example
60 in3/yr × 0.000165933758 = 0.0099560255 gal/fn
60 cubic inch per years = 0.0099560255 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 cubic inch per years?
1 cubic inch per years equals 0.0001659338 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per years to gallon per fortnight?
Multiply the cubic inch per years value by 0.000165933758. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to cubic inch per years?
Use the reverse factor: 1 gallon per fortnight equals 6,026.50125 cubic inch per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per years?
Cubic inch per Years (in3/yr) 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 years to gallon per fortnight conversion exact?
Yes. Both cubic inch per years and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.000165933758 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.
