About Converting Imperial quart per Hours to Imperial pints per Millisecond
Imperial quart per Hours and Imperial 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
imperial pints per millisecond = imperial quart per hours × 5.555556e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per hours equals 3.157007e-7 base units, and 1 imperial pint per millisecond equals 0.56826125 base units, so dividing one by the other gives the direct imperial quart per hours-to-imperial pint per millisecond factor of 5.555556e-7.
Simple example
1 imp qt/h × 5.555556e-7 = 5.555556e-7 imp pt/ms
1 imperial quart per hours = 5.555556e-7 imperial pints per millisecond.
Real-world example
60 imp qt/h × 5.555556e-7 = 0.0000333333 imp pt/ms
60 imperial quart per hours = 0.0000333333 imperial pints per millisecond.

Frequently asked questions
How many imperial pints per millisecond are in 1 imperial quart per hours?
1 imperial quart per hours equals 5.555556e-7 imperial pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to imperial pint per millisecond?
Multiply the imperial quart per hours value by 5.555556e-7. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per millisecond back to imperial quart per hours?
Use the reverse factor: 1 imperial pint per millisecond equals 1,800,000 imperial quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
What is a imperial pint per millisecond?
Imperial pint per Millisecond (imp pt/ms) is a unit of flow rate.
Is the imperial quart per hours to imperial pint per millisecond conversion exact?
Yes. Both imperial quart per hours and imperial pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 5.555556e-7 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.
