About Converting Pints per Millisecond to Imperial quart per Hours
Pint per Millisecond and Imperial quart per Hours 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 hours = pints per millisecond × 1498813.53233
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 hours equals 3.157007e-7 base units, so dividing one by the other gives the direct pint per millisecond-to-imperial quart per hours factor of 1498813.53233.
Simple example
1 pt/ms × 1498813.532 = 1,498,813.532 imp qt/h
1 pint per millisecond = 1,498,813.532 imperial quart per hours.
Real-world example
60 pt/ms × 1498813.532 = 89,928,811.94 imp qt/h
60 pints per millisecond = 89,928,811.94 imperial quart per hours.

Frequently asked questions
How many imperial quart per hours are in 1 pint per millisecond?
1 pint per millisecond equals 1,498,813.532 imperial quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to imperial quart per hours?
Multiply the pint per millisecond value by 1498813.532. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per hours back to pint per millisecond?
Use the reverse factor: 1 imperial quart per hours equals 6.671944e-7 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 hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
Is the pint per millisecond to imperial quart per hours conversion exact?
Yes. Both pint per millisecond and imperial quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 1498813.532 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.
