About Converting Cubic feet per Fortnight to Quart per Days
Cubic foot per Fortnight and Quart per Days 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
quart per days = cubic feet per fortnight × 2.13729128015
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per fortnight equals 2.341009e-8 base units, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct cubic foot per fortnight-to-quart per days factor of 2.13729128015.
Simple example
1 ft3/fn × 2.13729128 = 2.13729128 qt/d
1 cubic foot per fortnight = 2.13729128 quart per days.
Real-world example
60 ft3/fn × 2.13729128 = 128.2374768 qt/d
60 cubic feet per fortnight = 128.2374768 quart per days.

Frequently asked questions
How many quart per days are in 1 cubic foot per fortnight?
1 cubic foot per fortnight equals 2.13729128 quart per days, using the exact defined conversion factor rather than an estimate.

What is a cubic foot per fortnight?
Cubic foot per Fortnight (ft3/fn) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the cubic foot per fortnight to quart per days conversion exact?
Yes. Both cubic foot per fortnight and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 2.13729128 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.
