About Converting Pints per Fortnight to Liters per Millisecond
Pint 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 = pints per fortnight × 3.911843e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per fortnight equals 3.911843e-10 base units, and 1 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct pint per fortnight-to-liter per millisecond factor of 3.911843e-10.
Simple example
1 pt/fn × 3.911843e-10 = 3.911843e-10 L/ms
1 pint per fortnight = 3.911843e-10 liters per millisecond.
Real-world example
60 pt/fn × 3.911843e-10 = 2.347106e-8 L/ms
60 pints per fortnight = 2.347106e-8 liters per millisecond.

Frequently asked questions
How many liters per millisecond are in 1 pint per fortnight?
1 pint per fortnight equals 3.911843e-10 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per fortnight to liter per millisecond?
Multiply the pint per fortnight value by 3.911843e-10. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to pint per fortnight?
Use the reverse factor: 1 liter per millisecond equals 2,556,340,116 pints per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per fortnight?
Pint per Fortnight (pt/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 pint per fortnight to liter per millisecond conversion exact?
Yes. Both pint per fortnight and liter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3.911843e-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.
