About Converting Quarts per Millisecond to Pint per Days
Quart per Millisecond and 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
pint per days = quarts per millisecond × 172800000
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 pint per days equals 5.47658e-9 base units, so dividing one by the other gives the direct quart per millisecond-to-pint per days factor of 172800000.
Simple example
1 qt/ms × 172800000 = 172,800,000 pt/d
1 quart per millisecond = 172,800,000 pint per days.
Real-world example
60 qt/ms × 172800000 = 10,368,000,000 pt/d
60 quarts per millisecond = 10,368,000,000 pint per days.

Frequently asked questions
How many pint per days are in 1 quart per millisecond?
1 quart per millisecond equals 172,800,000 pint per days, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to pint per days?
Multiply the quart per millisecond value by 172800000. The converter above does this instantly to whatever precision you set.
How do I convert pint per days back to quart per millisecond?
Use the reverse factor: 1 pint per days equals 5.787037e-9 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
What is a pint per days?
Pint per Days (pt/d) is a unit of flow rate.
Is the quart per millisecond to pint per days conversion exact?
Yes. Both quart per millisecond and pint per days are defined by fixed standards rather than physical artifacts, so the factor of 172800000 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.
