About Converting Quart per Days to Pint per Seconds
Quart per Days and Pint per Seconds 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 seconds = quart per days × 0.0000231481481481
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 pint per seconds equals 0.000473176473 base units, so dividing one by the other gives the direct quart per days-to-pint per seconds factor of 0.0000231481481481.
Simple example
1 qt/d × 0.00002314814815 = 0.0000231481 pt/s
1 quart per days = 0.0000231481 pint per seconds.
Real-world example
60 qt/d × 0.00002314814815 = 0.0013888889 pt/s
60 quart per days = 0.0013888889 pint per seconds.

Frequently asked questions
How many pint per seconds are in 1 quart per days?
1 quart per days equals 0.0000231481 pint per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to pint per seconds?
Multiply the quart per days value by 0.00002314814815. The converter above does this instantly to whatever precision you set.
How do I convert pint per seconds back to quart per days?
Use the reverse factor: 1 pint per seconds equals 43,200 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a pint per seconds?
Pint per Seconds (pt/s) is a unit of flow rate.
Is the quart per days to pint per seconds conversion exact?
Yes. Both quart per days and pint per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00002314814815 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.
