About Converting Pint per Hours to Imperial quart per Hours
Pint per Hours 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 = pint per hours × 0.416337092314
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per hours equals 1.314379e-7 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 hours-to-imperial quart per hours factor of 0.416337092314.
Simple example
1 pt/h × 0.4163370923 = 0.4163370923 imp qt/h
1 pint per hours = 0.4163370923 imperial quart per hours.
Real-world example
60 pt/h × 0.4163370923 = 24.98022554 imp qt/h
60 pint per hours = 24.98022554 imperial quart per hours.

What is a pint per hours?
Pint per Hours (pt/h) 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 hours to imperial quart per hours conversion exact?
Yes. Both pint per hours and imperial quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.4163370923 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.
