About Converting Cups per Millisecond to Imperial gallon per Days
Cup per Millisecond and Imperial gallon 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 gallon per days = cups per millisecond × 4496440.597
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per millisecond equals 0.2365882365 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct cup per millisecond-to-imperial gallon per days factor of 4496440.597.
Simple example
1 cup/ms × 4496440.597 = 4,496,440.597 imp gal/d
1 cup per millisecond = 4,496,440.597 imperial gallon per days.
Real-world example
60 cup/ms × 4496440.597 = 269,786,435.8 imp gal/d
60 cups per millisecond = 269,786,435.8 imperial gallon per days.

Frequently asked questions
How many imperial gallon per days are in 1 cup per millisecond?
1 cup per millisecond equals 4,496,440.597 imperial gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per millisecond to imperial gallon per days?
Multiply the cup per millisecond value by 4496440.597. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per days back to cup per millisecond?
Use the reverse factor: 1 imperial gallon per days equals 2.223981e-7 cups per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per millisecond?
Cup per Millisecond (cup/ms) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the cup per millisecond to imperial gallon per days conversion exact?
Yes. Both cup per millisecond and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 4496440.597 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.
