About Converting Quart per Seconds to Gallons per Fortnight
Quart per Seconds and Gallon 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
gallons per fortnight = quart per seconds × 302400
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct quart per seconds-to-gallon per fortnight factor of 302400.
Simple example
1 qt/s × 302400 = 302,400 gal/fn
1 quart per seconds = 302,400 gallons per fortnight.
Real-world example
60 qt/s × 302400 = 18,144,000 gal/fn
60 quart per seconds = 18,144,000 gallons per fortnight.

Frequently asked questions
How many gallons per fortnight are in 1 quart per seconds?
1 quart per seconds equals 302,400 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to gallon per fortnight?
Multiply the quart per seconds value by 302400. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to quart per seconds?
Use the reverse factor: 1 gallon per fortnight equals 0.0000033069 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the quart per seconds to gallon per fortnight conversion exact?
Yes. Both quart per seconds and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 302400 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.
