About Converting Cubic inches per Fortnight to Gallon per Weeks
Cubic inch per Fortnight and Gallon per Weeks 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 weeks = cubic inches per fortnight × 0.0021645021645
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 weeks equals 6.258948e-9 base units, so dividing one by the other gives the direct cubic inch per fortnight-to-gallon per weeks factor of 0.0021645021645.
Simple example
1 in3/fn × 0.002164502165 = 0.0021645022 gal/wk
1 cubic inch per fortnight = 0.0021645022 gallon per weeks.
Real-world example
60 in3/fn × 0.002164502165 = 0.1298701299 gal/wk
60 cubic inches per fortnight = 0.1298701299 gallon per weeks.

How do I convert gallon per weeks back to cubic inch per fortnight?
Use the reverse factor: 1 gallon per weeks equals 462 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 weeks?
Gallon per Weeks (gal/wk) is a unit of flow rate.
Is the cubic inch per fortnight to gallon per weeks conversion exact?
Yes. Both cubic inch per fortnight and gallon per weeks are defined by fixed standards rather than physical artifacts, so the factor of 0.002164502165 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.
