About Converting Gallon per Minutes to Imperial pint per Hours
Gallon per Minutes and Imperial pint 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
imperial pint per hours = gallon per minutes × 399.683608622
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 imperial pint per hours equals 1.578503e-7 base units, so dividing one by the other gives the direct gallon per minutes-to-imperial pint per hours factor of 399.683608622.
Simple example
1 gal/min × 399.6836086 = 399.6836086 imp pt/h
1 gallon per minutes = 399.6836086 imperial pint per hours.
Real-world example
60 gal/min × 399.6836086 = 23,981.01652 imp pt/h
60 gallon per minutes = 23,981.01652 imperial pint per hours.

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.
