About Converting Imperial pint per Days to Quart per Seconds
Imperial pint per Days and Quart 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
quart per seconds = imperial pint per days × 0.00000694994169852
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial pint per days equals 6.577098e-9 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct imperial pint per days-to-quart per seconds factor of 0.00000694994169852.
Simple example
1 imp pt/d × 0.000006949941699 = 0.0000069499 qt/s
1 imperial pint per days = 0.0000069499 quart per seconds.
Real-world example
60 imp pt/d × 0.000006949941699 = 0.0004169965 qt/s
60 imperial pint per days = 0.0004169965 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 imperial pint per days?
1 imperial pint per days equals 0.0000069499 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial pint per days to quart per seconds?
Multiply the imperial pint per days value by 0.000006949941699. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to imperial pint per days?
Use the reverse factor: 1 quart per seconds equals 143,886.0991 imperial pint per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial pint per days?
Imperial pint per Days (imp pt/d) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the imperial pint per days to quart per seconds conversion exact?
Yes. Both imperial pint per days and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.000006949941699 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.
