About Converting Imperial pints per Millisecond to Imperial gallon per Seconds
Imperial pint per Millisecond and Imperial gallon per Seconds 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 seconds = imperial pints per millisecond × 125
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 seconds equals 0.00454609 base units, so dividing one by the other gives the direct imperial pint per millisecond-to-imperial gallon per seconds factor of 125.
Simple example
1 imp pt/ms × 125 = 125 imp gal/s
1 imperial pint per millisecond = 125 imperial gallon per seconds.
Real-world example
60 imp pt/ms × 125 = 7,500 imp gal/s
60 imperial pints per millisecond = 7,500 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 imperial pint per millisecond?
1 imperial pint per millisecond equals 125 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial pint per millisecond to imperial gallon per seconds?
Multiply the imperial pint per millisecond value by 125. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to imperial pint per millisecond?
Use the reverse factor: 1 imperial gallon per seconds equals 0.008 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 seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the imperial pint per millisecond to imperial gallon per seconds conversion exact?
Yes. Both imperial pint per millisecond and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 125 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.
