About Converting Pint per Seconds to Quarts per Millisecond
Pint per Seconds and 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
quarts per millisecond = pint per seconds × 0.0005
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 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct pint per seconds-to-quart per millisecond factor of 0.0005.
Simple example
1 pt/s × 0.0005 = 0.0005 qt/ms
1 pint per seconds = 0.0005 quarts per millisecond.
Real-world example
60 pt/s × 0.0005 = 0.03 qt/ms
60 pint per seconds = 0.03 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 pint per seconds?
1 pint per seconds equals 0.0005 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per seconds to quart per millisecond?
Multiply the pint per seconds value by 0.0005. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to pint per seconds?
Use the reverse factor: 1 quart per millisecond equals 2,000 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 quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the pint per seconds to quart per millisecond conversion exact?
Yes. Both pint per seconds and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0005 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.
