About Converting Imperial pint per Days to Cup per Days
Imperial pint per Days and Cup 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
cup per days = imperial pint per days × 2.40189985101
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 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct imperial pint per days-to-cup per days factor of 2.40189985101.
Simple example
1 imp pt/d × 2.401899851 = 2.401899851 cup/d
1 imperial pint per days = 2.401899851 cup per days.
Real-world example
60 imp pt/d × 2.401899851 = 144.1139911 cup/d
60 imperial pint per days = 144.1139911 cup per days.

What is a imperial pint per days?
Imperial pint per Days (imp pt/d) is a unit of flow rate.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the imperial pint per days to cup per days conversion exact?
Yes. Both imperial pint per days and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 2.401899851 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.
