About Converting Pint per Hours to Pints per Millisecond
Pint per Hours and 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
pints per millisecond = pint per hours × 2.777778e-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 pint per millisecond equals 0.473176473 base units, so dividing one by the other gives the direct pint per hours-to-pint per millisecond factor of 2.777778e-7.
Simple example
1 pt/h × 2.777778e-7 = 2.777778e-7 pt/ms
1 pint per hours = 2.777778e-7 pints per millisecond.
Real-world example
60 pt/h × 2.777778e-7 = 0.0000166667 pt/ms
60 pint per hours = 0.0000166667 pints per millisecond.

Frequently asked questions
How many pints per millisecond are in 1 pint per hours?
1 pint per hours equals 2.777778e-7 pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to pint per millisecond?
Multiply the pint per hours value by 2.777778e-7. The converter above does this instantly to whatever precision you set.
How do I convert pint per millisecond back to pint per hours?
Use the reverse factor: 1 pint per millisecond equals 3,600,000 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 pint per millisecond?
Pint per Millisecond (pt/ms) is a unit of flow rate.
Is the pint per hours to pint per millisecond conversion exact?
Yes. Both pint per hours and pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.777778e-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.
