About Converting Cup per Days to Imperial pints per Millisecond
Cup per Days and Imperial pint per Millisecond 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 pints per millisecond = cup per days × 4.818716e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 imperial pint per millisecond equals 0.56826125 base units, so dividing one by the other gives the direct cup per days-to-imperial pint per millisecond factor of 4.818716e-9.
Simple example
1 cup/d × 4.818716e-9 = 4.818716e-9 imp pt/ms
1 cup per days = 4.818716e-9 imperial pints per millisecond.
Real-world example
60 cup/d × 4.818716e-9 = 2.89123e-7 imp pt/ms
60 cup per days = 2.89123e-7 imperial pints per millisecond.

Frequently asked questions
How many imperial pints per millisecond are in 1 cup per days?
1 cup per days equals 4.818716e-9 imperial pints per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to imperial pint per millisecond?
Multiply the cup per days value by 4.818716e-9. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per millisecond back to cup per days?
Use the reverse factor: 1 imperial pint per millisecond equals 207,524,147.1 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a imperial pint per millisecond?
Imperial pint per Millisecond (imp pt/ms) is a unit of flow rate.
Is the cup per days to imperial pint per millisecond conversion exact?
Yes. Both cup per days and imperial pint per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.818716e-9 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.
