About Converting Quarts per Fortnight to Liters per Millisecond
Quart per Fortnight and Liter per Millisecond 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
liters per millisecond = 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 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct quart per fortnight-to-liter per millisecond factor of 7.823685e-10.
Simple example
1 qt/fn × 7.823685e-10 = 7.823685e-10 L/ms
1 quart per fortnight = 7.823685e-10 liters per millisecond.
Real-world example
60 qt/fn × 7.823685e-10 = 4.694211e-8 L/ms
60 quarts per fortnight = 4.694211e-8 liters per millisecond.

Frequently asked questions
How many liters per millisecond are in 1 quart per fortnight?
1 quart per fortnight equals 7.823685e-10 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per fortnight to liter per millisecond?
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 liter per millisecond back to quart per fortnight?
Use the reverse factor: 1 liter per millisecond 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 liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the quart per fortnight to liter per millisecond conversion exact?
Yes. Both quart per fortnight and liter per millisecond 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.
