About Converting Pint per Hours to Quart per Hours
Pint per Hours and 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
quart per hours = pint per hours × 0.5
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 quart per hours equals 2.628758e-7 base units, so dividing one by the other gives the direct pint per hours-to-quart per hours factor of 0.5.
Simple example
1 pt/h × 0.5 = 0.5 qt/h
1 pint per hours = 0.5 quart per hours.
Real-world example
60 pt/h × 0.5 = 30 qt/h
60 pint per hours = 30 quart per hours.

Frequently asked questions
How many quart per hours are in 1 pint per hours?
1 pint per hours equals 0.5 quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to quart per hours?
Multiply the pint per hours value by 0.5. The converter above does this instantly to whatever precision you set.
How do I convert quart per hours back to pint per hours?
Use the reverse factor: 1 quart per hours equals 2 pint per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per hours?
Pint per Hours (pt/h) is a unit of flow rate.
What is a quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the pint per hours to quart per hours conversion exact?
Yes. Both pint per hours and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.5 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.
