About Converting Quart per Days to Imperial pint per Days
Quart per Days and Imperial 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
imperial pint per days = quart per days × 1.66534836926
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 imperial pint per days equals 6.577098e-9 base units, so dividing one by the other gives the direct quart per days-to-imperial pint per days factor of 1.66534836926.
Simple example
1 qt/d × 1.665348369 = 1.665348369 imp pt/d
1 quart per days = 1.665348369 imperial pint per days.
Real-world example
60 qt/d × 1.665348369 = 99.92090216 imp pt/d
60 quart per days = 99.92090216 imperial pint per days.

How do I convert imperial pint per days back to quart per days?
Use the reverse factor: 1 imperial pint per days equals 0.6004749628 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 imperial pint per days?
Imperial pint per Days (imp pt/d) is a unit of flow rate.
Is the quart per days to imperial pint per days conversion exact?
Yes. Both quart per days and imperial pint per days are defined by fixed standards rather than physical artifacts, so the factor of 1.665348369 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.
