About Converting Pints per Millisecond to Imperial quart per Days
Pint per Millisecond and Imperial quart 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 quart per days = pints per millisecond × 35971524.776
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 imperial quart per days equals 1.31542e-8 base units, so dividing one by the other gives the direct pint per millisecond-to-imperial quart per days factor of 35971524.776.
Simple example
1 pt/ms × 35971524.78 = 35,971,524.78 imp qt/d
1 pint per millisecond = 35,971,524.78 imperial quart per days.
Real-world example
60 pt/ms × 35971524.78 = 2,158,291,487 imp qt/d
60 pints per millisecond = 2,158,291,487 imperial quart per days.

Frequently asked questions
How many imperial quart per days are in 1 pint per millisecond?
1 pint per millisecond equals 35,971,524.78 imperial quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert pint per millisecond to imperial quart per days?
Multiply the pint per millisecond value by 35971524.78. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per days back to pint per millisecond?
Use the reverse factor: 1 imperial quart per days equals 2.779977e-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 imperial quart per days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
Is the pint per millisecond to imperial quart per days conversion exact?
Yes. Both pint per millisecond and imperial quart per days are defined by fixed standards rather than physical artifacts, so the factor of 35971524.78 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.
