About Converting Cubic inch per Hours to Quarts per Fortnight
Cubic inch per Hours and Quart 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
quarts per fortnight = cubic inch per hours × 5.81818181818
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 quart per fortnight equals 7.823685e-10 base units, so dividing one by the other gives the direct cubic inch per hours-to-quart per fortnight factor of 5.81818181818.
Simple example
1 in3/h × 5.818181818 = 5.818181818 qt/fn
1 cubic inch per hours = 5.818181818 quarts per fortnight.
Real-world example
60 in3/h × 5.818181818 = 349.0909091 qt/fn
60 cubic inch per hours = 349.0909091 quarts per fortnight.

Frequently asked questions
How many quarts per fortnight are in 1 cubic inch per hours?
1 cubic inch per hours equals 5.818181818 quarts per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to quart per fortnight?
Multiply the cubic inch per hours value by 5.818181818. The converter above does this instantly to whatever precision you set.
How do I convert quart per fortnight back to cubic inch per hours?
Use the reverse factor: 1 quart per fortnight equals 0.171875 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/h) is a unit of flow rate.
What is a quart per fortnight?
Quart per Fortnight (qt/fn) is a unit of flow rate.
Is the cubic inch per hours to quart per fortnight conversion exact?
Yes. Both cubic inch per hours and quart per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 5.818181818 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.
