About Converting Imperial pints per Millisecond to Imperial gallon per Hours
Imperial 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 = imperial pints per millisecond × 450000
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial pint per millisecond equals 0.56826125 base units, and 1 imperial gallon per hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct imperial pint per millisecond-to-imperial gallon per hours factor of 450000.
Simple example
1 imp pt/ms × 450000 = 450,000 imp gal/h
1 imperial pint per millisecond = 450,000 imperial gallon per hours.
Real-world example
60 imp pt/ms × 450000 = 27,000,000 imp gal/h
60 imperial pints per millisecond = 27,000,000 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 imperial pint per millisecond?
1 imperial pint per millisecond equals 450,000 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial pint per millisecond to imperial gallon per hours?
Multiply the imperial pint per millisecond value by 450000. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to imperial pint per millisecond?
Use the reverse factor: 1 imperial gallon per hours equals 0.0000022222 imperial pints per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial pint per millisecond?
Imperial pint per Millisecond (imp 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 imperial pint per millisecond to imperial gallon per hours conversion exact?
Yes. Both imperial pint per millisecond and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 450000 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.
