About Converting Quart per Days to Cubic inches per Fortnight
Quart per Days and Cubic inch 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
cubic inches per fortnight = quart per days × 808.5
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 cubic inch per fortnight equals 1.354751e-11 base units, so dividing one by the other gives the direct quart per days-to-cubic inch per fortnight factor of 808.5.
Simple example
1 qt/d × 808.5 = 808.5 in3/fn
1 quart per days = 808.5 cubic inches per fortnight.
Real-world example
60 qt/d × 808.5 = 48,510 in3/fn
60 quart per days = 48,510 cubic inches per fortnight.

Frequently asked questions
How many cubic inches per fortnight are in 1 quart per days?
1 quart per days equals 808.5 cubic inches per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to cubic inch per fortnight?
Multiply the quart per days value by 808.5. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per fortnight back to quart per days?
Use the reverse factor: 1 cubic inch per fortnight equals 0.0012368584 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a cubic inch per fortnight?
Cubic inch per Fortnight (in3/fn) is a unit of flow rate.
Is the quart per days to cubic inch per fortnight conversion exact?
Yes. Both quart per days and cubic inch per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 808.5 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.
