About Converting Quarts per Fortnight to Gallon per Days
Quart per Fortnight and Gallon 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
gallon per days = quarts per fortnight × 0.0178571428571
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per fortnight equals 7.823685e-10 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct quart per fortnight-to-gallon per days factor of 0.0178571428571.
Simple example
1 qt/fn × 0.01785714286 = 0.0178571429 gal/d
1 quart per fortnight = 0.0178571429 gallon per days.
Real-world example
60 qt/fn × 0.01785714286 = 1.071428571 gal/d
60 quarts per fortnight = 1.071428571 gallon per days.

Frequently asked questions
How many gallon per days are in 1 quart per fortnight?
1 quart per fortnight equals 0.0178571429 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert quart per fortnight to gallon per days?
Multiply the quart per fortnight value by 0.01785714286. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to quart per fortnight?
Use the reverse factor: 1 gallon per days equals 56 quarts per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per fortnight?
Quart per Fortnight (qt/fn) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the quart per fortnight to gallon per days conversion exact?
Yes. Both quart per fortnight and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 0.01785714286 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.
