About Converting Pints per Fortnight to Cubic inch per Seconds
Pint per Fortnight and Cubic inch 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 inch per seconds = pints per fortnight × 0.0000238715277778
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 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct pint per fortnight-to-cubic inch per seconds factor of 0.0000238715277778.
Simple example
1 pt/fn × 0.00002387152778 = 0.0000238715 in3/s
1 pint per fortnight = 0.0000238715 cubic inch per seconds.
Real-world example
60 pt/fn × 0.00002387152778 = 0.0014322917 in3/s
60 pints per fortnight = 0.0014322917 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 pint per fortnight?
1 pint per fortnight equals 0.0000238715 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert pint per fortnight to cubic inch per seconds?
Multiply the pint per fortnight value by 0.00002387152778. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to pint per fortnight?
Use the reverse factor: 1 cubic inch per seconds equals 41,890.90909 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 cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
Is the pint per fortnight to cubic inch per seconds conversion exact?
Yes. Both pint per fortnight and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00002387152778 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.
