About Converting Gallons per Millisecond to Imperial pint per Days
Gallon per Millisecond and Imperial pint 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
imperial pint per days = gallons per millisecond × 575544396.416
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 imperial pint per days equals 6.577098e-9 base units, so dividing one by the other gives the direct gallon per millisecond-to-imperial pint per days factor of 575544396.416.
Simple example
1 gal/ms × 575544396.4 = 575,544,396.4 imp pt/d
1 gallon per millisecond = 575,544,396.4 imperial pint per days.
Real-world example
60 gal/ms × 575544396.4 = 34,532,663,780 imp pt/d
60 gallons per millisecond = 34,532,663,780 imperial pint per days.

Frequently asked questions
How many imperial pint per days are in 1 gallon per millisecond?
1 gallon per millisecond equals 575,544,396.4 imperial pint per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to imperial pint per days?
Multiply the gallon per millisecond value by 575544396.4. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per days back to gallon per millisecond?
Use the reverse factor: 1 imperial pint per days equals 1.737485e-9 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a imperial pint per days?
Imperial pint per Days (imp pt/d) is a unit of flow rate.
Is the gallon per millisecond to imperial pint per days conversion exact?
Yes. Both gallon per millisecond and imperial pint per days are defined by fixed standards rather than physical artifacts, so the factor of 575544396.4 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.
