About Converting Pints per Millisecond to Cubic inch per Seconds
Pint per Millisecond 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 millisecond × 28875
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per millisecond equals 0.473176473 base units, and 1 cubic inch per seconds equals 0.000016387064 base units, so dividing one by the other gives the direct pint per millisecond-to-cubic inch per seconds factor of 28875.
Simple example
1 pt/ms × 28875 = 28,875 in3/s
1 pint per millisecond = 28,875 cubic inch per seconds.
Real-world example
60 pt/ms × 28875 = 1,732,500 in3/s
60 pints per millisecond = 1,732,500 cubic inch per seconds.

Frequently asked questions
How many cubic inch per seconds are in 1 pint per millisecond?
1 pint per millisecond equals 28,875 cubic inch per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to cubic inch per seconds?
Multiply the pint per millisecond value by 28875. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per seconds back to pint per millisecond?
Use the reverse factor: 1 cubic inch per seconds equals 0.000034632 pints per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per millisecond?
Pint per Millisecond (pt/ms) 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 millisecond to cubic inch per seconds conversion exact?
Yes. Both pint per millisecond and cubic inch per seconds are defined by fixed standards rather than physical artifacts, so the factor of 28875 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.
