About Converting Pint per Hours to Imperial pints per Millisecond
Pint 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 = pint per hours × 2.312984e-7
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 pint per millisecond equals 0.56826125 base units, so dividing one by the other gives the direct pint per hours-to-imperial pint per millisecond factor of 2.312984e-7.
Simple example
1 pt/h × 2.312984e-7 = 2.312984e-7 imp pt/ms
1 pint per hours = 2.312984e-7 imperial pints per millisecond.
Real-world example
60 pt/h × 2.312984e-7 = 0.0000138779 imp pt/ms
60 pint per hours = 0.0000138779 imperial pints per millisecond.

Frequently asked questions
How many imperial pints per millisecond are in 1 pint per hours?
1 pint per hours equals 2.312984e-7 imperial pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to imperial pint per millisecond?
Multiply the pint per hours value by 2.312984e-7. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per millisecond back to pint per hours?
Use the reverse factor: 1 imperial pint per millisecond equals 4,323,419.732 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 imperial pint per millisecond?
Imperial pint per Millisecond (imp pt/ms) is a unit of flow rate.
Is the pint per hours to imperial pint per millisecond conversion exact?
Yes. Both pint per hours and imperial pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.312984e-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.
