About Converting Pints per Fortnight to Quarts per Millisecond
Pint per Fortnight and Quart 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
quarts per millisecond = pints per fortnight × 4.133598e-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 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct pint per fortnight-to-quart per millisecond factor of 4.133598e-10.
Simple example
1 pt/fn × 4.133598e-10 = 4.133598e-10 qt/ms
1 pint per fortnight = 4.133598e-10 quarts per millisecond.
Real-world example
60 pt/fn × 4.133598e-10 = 2.480159e-8 qt/ms
60 pints per fortnight = 2.480159e-8 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 pint per fortnight?
1 pint per fortnight equals 4.133598e-10 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per fortnight to quart per millisecond?
Multiply the pint per fortnight value by 4.133598e-10. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to pint per fortnight?
Use the reverse factor: 1 quart per millisecond equals 2,419,200,000 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 quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the pint per fortnight to quart per millisecond conversion exact?
Yes. Both pint per fortnight and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.133598e-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.
