About Converting Gallon per Minutes to Pints per Millisecond
Gallon per Minutes and Pint per Millisecond 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
pints per millisecond = gallon per minutes × 0.000133333333333
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 pint per millisecond equals 0.473176473 base units, so dividing one by the other gives the direct gallon per minutes-to-pint per millisecond factor of 0.000133333333333.
Simple example
1 gal/min × 0.0001333333333 = 0.0001333333 pt/ms
1 gallon per minutes = 0.0001333333 pints per millisecond.
Real-world example
60 gal/min × 0.0001333333333 = 0.008 pt/ms
60 gallon per minutes = 0.008 pints per millisecond.
Conversion table
| Gallon per Minutes (gal/min) | Pint per Millisecond (pt/ms) |
|---|---|
| 0.1 gal/min | 0.0000133333 pt/ms |
| 1 gal/min | 0.0001333333 pt/ms |
| 10 gal/min | 0.0013333333 pt/ms |
| 60 gal/min | 0.008 pt/ms |
| 100 gal/min | 0.0133333333 pt/ms |

Reverse conversion: Pint per Millisecond to Gallon per Minutes
0.0001333333 pt/ms × 7500 = 0.99999975 gal/min
0.0001333333 pints per millisecond = 0.99999975 gallon per minutes.
gallon per minutes = pints per millisecond × 7500

Frequently asked questions
How many pints per millisecond are in 1 gallon per minutes?
1 gallon per minutes equals 0.0001333333 pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to pint per millisecond?
Multiply the gallon per minutes value by 0.0001333333333. The converter above does this instantly to whatever precision you set.
How do I convert pint per millisecond back to gallon per minutes?
Use the reverse factor: 1 pint per millisecond equals 7,500 gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a pint per millisecond?
Pint per Millisecond (pt/ms) is a unit of flow rate.
Is the gallon per minutes to pint per millisecond conversion exact?
Yes. Both gallon per minutes and pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0001333333333 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
