About Converting Pints per Fortnight to Cubic inches per Millisecond
Pint per Fortnight and Cubic inch 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
cubic inches per millisecond = pints per fortnight × 2.387153e-8
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 millisecond equals 0.016387064 base units, so dividing one by the other gives the direct pint per fortnight-to-cubic inch per millisecond factor of 2.387153e-8.
Simple example
1 pt/fn × 2.387153e-8 = 2.387153e-8 in3/ms
1 pint per fortnight = 2.387153e-8 cubic inches per millisecond.
Real-world example
60 pt/fn × 2.387153e-8 = 0.0000014323 in3/ms
60 pints per fortnight = 0.0000014323 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 pint per fortnight?
1 pint per fortnight equals 2.387153e-8 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per fortnight to cubic inch per millisecond?
Multiply the pint per fortnight value by 2.387153e-8. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to pint per fortnight?
Use the reverse factor: 1 cubic inch per millisecond equals 41,890,909.09 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 millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the pint per fortnight to cubic inch per millisecond conversion exact?
Yes. Both pint per fortnight and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.387153e-8 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.
