About Converting Imperial pint per Days to Cups per Millisecond
Imperial pint per Days and Cup 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
cups per millisecond = imperial pint per days × 2.779977e-8
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 millisecond equals 0.2365882365 base units, so dividing one by the other gives the direct imperial pint per days-to-cup per millisecond factor of 2.779977e-8.
Simple example
1 imp pt/d × 2.779977e-8 = 2.779977e-8 cup/ms
1 imperial pint per days = 2.779977e-8 cups per millisecond.
Real-world example
60 imp pt/d × 2.779977e-8 = 0.000001668 cup/ms
60 imperial pint per days = 0.000001668 cups per millisecond.

Frequently asked questions
How many cups per millisecond are in 1 imperial pint per days?
1 imperial pint per days equals 2.779977e-8 cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial pint per days to cup per millisecond?
Multiply the imperial pint per days value by 2.779977e-8. The converter above does this instantly to whatever precision you set.
How do I convert cup per millisecond back to imperial pint per days?
Use the reverse factor: 1 cup per millisecond equals 35,971,524.78 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 cup per millisecond?
Cup per Millisecond (cup/ms) is a unit of flow rate.
Is the imperial pint per days to cup per millisecond conversion exact?
Yes. Both imperial pint per days and cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.779977e-8 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.
