About Converting Pint per Hours to Quart per Seconds
Pint per Hours and Quart per Seconds 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 seconds = pint per hours × 0.000138888888889
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 seconds equals 0.000946352946 base units, so dividing one by the other gives the direct pint per hours-to-quart per seconds factor of 0.000138888888889.
Simple example
1 pt/h × 0.0001388888889 = 0.0001388889 qt/s
1 pint per hours = 0.0001388889 quart per seconds.
Real-world example
60 pt/h × 0.0001388888889 = 0.0083333333 qt/s
60 pint per hours = 0.0083333333 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 pint per hours?
1 pint per hours equals 0.0001388889 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to quart per seconds?
Multiply the pint per hours value by 0.0001388888889. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to pint per hours?
Use the reverse factor: 1 quart per seconds equals 7,200 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 seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the pint per hours to quart per seconds conversion exact?
Yes. Both pint per hours and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0001388888889 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.
