About Converting Pints per Millisecond to Imperial quart per Seconds
Pint per Millisecond and Imperial quart 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
imperial quart per seconds = pints per millisecond × 416.337092314
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 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct pint per millisecond-to-imperial quart per seconds factor of 416.337092314.
Simple example
1 pt/ms × 416.3370923 = 416.3370923 imp qt/s
1 pint per millisecond = 416.3370923 imperial quart per seconds.
Real-world example
60 pt/ms × 416.3370923 = 24,980.22554 imp qt/s
60 pints per millisecond = 24,980.22554 imperial quart per seconds.

Frequently asked questions
How many imperial quart per seconds are in 1 pint per millisecond?
1 pint per millisecond equals 416.3370923 imperial quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to imperial quart per seconds?
Multiply the pint per millisecond value by 416.3370923. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per seconds back to pint per millisecond?
Use the reverse factor: 1 imperial quart per seconds equals 0.0024018999 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 imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
Is the pint per millisecond to imperial quart per seconds conversion exact?
Yes. Both pint per millisecond and imperial quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 416.3370923 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.
