About Converting Pints per Millisecond to Gallon per Days
Pint per Millisecond and Gallon per Days 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 days = pints per millisecond × 10800000
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 days equals 4.381264e-8 base units, so dividing one by the other gives the direct pint per millisecond-to-gallon per days factor of 10800000.
Simple example
1 pt/ms × 10800000 = 10,800,000 gal/d
1 pint per millisecond = 10,800,000 gallon per days.
Real-world example
60 pt/ms × 10800000 = 648,000,000 gal/d
60 pints per millisecond = 648,000,000 gallon per days.

Frequently asked questions
How many gallon per days are in 1 pint per millisecond?
1 pint per millisecond equals 10,800,000 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to gallon per days?
Multiply the pint per millisecond value by 10800000. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to pint per millisecond?
Use the reverse factor: 1 gallon per days equals 9.259259e-8 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 days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the pint per millisecond to gallon per days conversion exact?
Yes. Both pint per millisecond and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 10800000 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.
