About Converting Imperial gallon per Days to Pints per Millisecond
Imperial gallon per Days 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. Both are volumetric flow rate units.
Formula
pints per millisecond = imperial gallon per days × 1.111991e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 pint per millisecond equals 0.473176473 base units, so dividing one by the other gives the direct imperial gallon per days-to-pint per millisecond factor of 1.111991e-7.
Simple example
1 imp gal/d × 1.111991e-7 = 1.111991e-7 pt/ms
1 imperial gallon per days = 1.111991e-7 pints per millisecond.
Real-world example
60 imp gal/d × 1.111991e-7 = 0.0000066719 pt/ms
60 imperial gallon per days = 0.0000066719 pints per millisecond.

Frequently asked questions
How many pints per millisecond are in 1 imperial gallon per days?
1 imperial gallon per days equals 1.111991e-7 pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per days to pint per millisecond?
Multiply the imperial gallon per days value by 1.111991e-7. The converter above does this instantly to whatever precision you set.
How do I convert pint per millisecond back to imperial gallon per days?
Use the reverse factor: 1 pint per millisecond equals 8,992,881.194 imperial gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
What is a pint per millisecond?
Pint per Millisecond (pt/ms) is a unit of flow rate.
Is the imperial gallon per days to pint per millisecond conversion exact?
Yes. Both imperial gallon per days and pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.111991e-7 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.
