About Converting Pint per Seconds to Imperial quarts per Millisecond
Pint per Seconds and Imperial 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
imperial quarts per millisecond = pint per seconds × 0.000416337092314
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per seconds equals 0.000473176473 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct pint per seconds-to-imperial quart per millisecond factor of 0.000416337092314.
Simple example
1 pt/s × 0.0004163370923 = 0.0004163371 imp qt/ms
1 pint per seconds = 0.0004163371 imperial quarts per millisecond.
Real-world example
60 pt/s × 0.0004163370923 = 0.0249802255 imp qt/ms
60 pint per seconds = 0.0249802255 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 pint per seconds?
1 pint per seconds equals 0.0004163371 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per seconds to imperial quart per millisecond?
Multiply the pint per seconds value by 0.0004163370923. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to pint per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 2,401.899851 pint per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per seconds?
Pint per Seconds (pt/s) is a unit of flow rate.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the pint per seconds to imperial quart per millisecond conversion exact?
Yes. Both pint per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0004163370923 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.
