About Converting Pints per Millisecond to Gallon per Minutes
Pint per Millisecond and Gallon per Minutes 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
gallon per minutes = pints per millisecond × 7500
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 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct pint per millisecond-to-gallon per minutes factor of 7500.
Simple example
1 pt/ms × 7500 = 7,500 gal/min
1 pint per millisecond = 7,500 gallon per minutes.
Real-world example
60 pt/ms × 7500 = 450,000 gal/min
60 pints per millisecond = 450,000 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 pint per millisecond?
1 pint per millisecond equals 7,500 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to gallon per minutes?
Multiply the pint per millisecond value by 7500. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to pint per millisecond?
Use the reverse factor: 1 gallon per minutes equals 0.0001333333 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 gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the pint per millisecond to gallon per minutes conversion exact?
Yes. Both pint per millisecond and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 7500 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.
