About Converting Quart per Seconds to Pint per Days
Quart per Seconds 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 = quart per seconds × 172800
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 pint per days equals 5.47658e-9 base units, so dividing one by the other gives the direct quart per seconds-to-pint per days factor of 172800.
Simple example
1 qt/s × 172800 = 172,800 pt/d
1 quart per seconds = 172,800 pint per days.
Real-world example
60 qt/s × 172800 = 10,368,000 pt/d
60 quart per seconds = 10,368,000 pint per days.

Frequently asked questions
How many pint per days are in 1 quart per seconds?
1 quart per seconds equals 172,800 pint per days, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to pint per days?
Multiply the quart per seconds value by 172800. The converter above does this instantly to whatever precision you set.
How do I convert pint per days back to quart per seconds?
Use the reverse factor: 1 pint per days equals 0.000005787 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) 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 seconds to pint per days conversion exact?
Yes. Both quart per seconds and pint per days are defined by fixed standards rather than physical artifacts, so the factor of 172800 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.
