About Converting Quarts per Fortnight to Cubic Meter per Seconds
Quart per Fortnight and Cubic Meter per Seconds 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 meter per seconds = quarts per fortnight × 7.823685e-10
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 cubic meter per seconds equals 1 base unit, so dividing one by the other gives the direct quart per fortnight-to-cubic meter per seconds factor of 7.823685e-10.
Simple example
1 qt/fn × 7.823685e-10 = 7.823685e-10 m3/s
1 quart per fortnight = 7.823685e-10 cubic meter per seconds.
Real-world example
60 qt/fn × 7.823685e-10 = 4.694211e-8 m3/s
60 quarts per fortnight = 4.694211e-8 cubic meter per seconds.

Frequently asked questions
How many cubic meter per seconds are in 1 quart per fortnight?
1 quart per fortnight equals 7.823685e-10 cubic meter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per fortnight to cubic meter per seconds?
Multiply the quart per fortnight value by 7.823685e-10. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per seconds back to quart per fortnight?
Use the reverse factor: 1 cubic meter per seconds equals 1,278,170,058 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 cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
Is the quart per fortnight to cubic meter per seconds conversion exact?
Yes. Both quart per fortnight and cubic meter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 7.823685e-10 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.
