About Converting Pint per Days to Cup per Seconds
Pint per Days and Cup 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
cup per seconds = pint per days × 0.0000231481481481
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per days equals 5.47658e-9 base units, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct pint per days-to-cup per seconds factor of 0.0000231481481481.
Simple example
1 pt/d × 0.00002314814815 = 0.0000231481 cup/s
1 pint per days = 0.0000231481 cup per seconds.
Real-world example
60 pt/d × 0.00002314814815 = 0.0013888889 cup/s
60 pint per days = 0.0013888889 cup per seconds.

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