About Converting Imperial quart per Minutes to Pints per Millisecond
Imperial quart per Minutes and Pint 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
pints per millisecond = imperial quart per minutes × 0.0000400316641835
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per minutes equals 0.0000189420416667 base units, and 1 pint per millisecond equals 0.473176473 base units, so dividing one by the other gives the direct imperial quart per minutes-to-pint per millisecond factor of 0.0000400316641835.
Simple example
1 imp qt/min × 0.00004003166418 = 0.0000400317 pt/ms
1 imperial quart per minutes = 0.0000400317 pints per millisecond.
Real-world example
60 imp qt/min × 0.00004003166418 = 0.0024018999 pt/ms
60 imperial quart per minutes = 0.0024018999 pints per millisecond.

Frequently asked questions
How many pints per millisecond are in 1 imperial quart per minutes?
1 imperial quart per minutes equals 0.0000400317 pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per minutes to pint per millisecond?
Multiply the imperial quart per minutes value by 0.00004003166418. The converter above does this instantly to whatever precision you set.
How do I convert pint per millisecond back to imperial quart per minutes?
Use the reverse factor: 1 pint per millisecond equals 24,980.22554 imperial quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per minutes?
Imperial quart per Minutes (imp qt/min) is a unit of flow rate.
What is a pint per millisecond?
Pint per Millisecond (pt/ms) is a unit of flow rate.
Is the imperial quart per minutes to pint per millisecond conversion exact?
Yes. Both imperial quart per minutes and pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00004003166418 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.
