About Converting Cubic inch per Weeks to Gallons per Fortnight
Cubic inch per Weeks 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 weeks × 0.00865800865801
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per weeks equals 2.709501e-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 weeks-to-gallon per fortnight factor of 0.00865800865801.
Simple example
1 in3/wk × 0.008658008658 = 0.0086580087 gal/fn
1 cubic inch per weeks = 0.0086580087 gallons per fortnight.
Real-world example
60 in3/wk × 0.008658008658 = 0.5194805195 gal/fn
60 cubic inch per weeks = 0.5194805195 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 cubic inch per weeks?
1 cubic inch per weeks equals 0.0086580087 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 weeks?
Use the reverse factor: 1 gallon per fortnight equals 115.5 cubic inch per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per weeks?
Cubic inch per Weeks (in3/wk) 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 weeks to gallon per fortnight conversion exact?
Yes. Both cubic inch per weeks and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 0.008658008658 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.
