About Converting Pint per Hours to Fluid ounces per Millisecond
Pint per Hours and Fluid ounce 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
fluid ounces per millisecond = pint per hours × 0.00000444444444444
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 fluid ounce per millisecond equals 0.0295735295625 base units, so dividing one by the other gives the direct pint per hours-to-fluid ounce per millisecond factor of 0.00000444444444444.
Simple example
1 pt/h × 0.000004444444444 = 0.0000044444 fl oz/ms
1 pint per hours = 0.0000044444 fluid ounces per millisecond.
Real-world example
60 pt/h × 0.000004444444444 = 0.0002666667 fl oz/ms
60 pint per hours = 0.0002666667 fluid ounces per millisecond.

Frequently asked questions
How many fluid ounces per millisecond are in 1 pint per hours?
1 pint per hours equals 0.0000044444 fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to fluid ounce per millisecond?
Multiply the pint per hours value by 0.000004444444444. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per millisecond back to pint per hours?
Use the reverse factor: 1 fluid ounce per millisecond equals 225,000 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 fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) is a unit of flow rate.
Is the pint per hours to fluid ounce per millisecond conversion exact?
Yes. Both pint per hours and fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000004444444444 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.
