About Converting Pints per Millisecond to Imperial gallon per Hours
Pint per Millisecond and Imperial gallon 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
imperial gallon per hours = pints per millisecond × 374703.383083
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per millisecond equals 0.473176473 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct pint per millisecond-to-imperial gallon per hours factor of 374703.383083.
Simple example
1 pt/ms × 374703.3831 = 374,703.3831 imp gal/h
1 pint per millisecond = 374,703.3831 imperial gallon per hours.
Real-world example
60 pt/ms × 374703.3831 = 22,482,202.98 imp gal/h
60 pints per millisecond = 22,482,202.98 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 pint per millisecond?
1 pint per millisecond equals 374,703.3831 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to imperial gallon per hours?
Multiply the pint per millisecond value by 374703.3831. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to pint per millisecond?
Use the reverse factor: 1 imperial gallon per hours equals 0.0000026688 pints per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per millisecond?
Pint per Millisecond (pt/ms) is a unit of flow rate.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the pint per millisecond to imperial gallon per hours conversion exact?
Yes. Both pint per millisecond and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 374703.3831 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.
