About Converting Imperial gallons per Millisecond to Cup per Days
Imperial gallon per Millisecond 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 gallons per millisecond × 1660193177.02
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per millisecond equals 4.54609 base units, and 1 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cup per days factor of 1660193177.02.
Simple example
1 imp gal/ms × 1660193177 = 1,660,193,177 cup/d
1 imperial gallon per millisecond = 1,660,193,177 cup per days.
Real-world example
60 imp gal/ms × 1660193177 = 99,611,590,620 cup/d
60 imperial gallons per millisecond = 99,611,590,620 cup per days.

Frequently asked questions
How many cup per days are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 1,660,193,177 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cup per days?
Multiply the imperial gallon per millisecond value by 1660193177. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to imperial gallon per millisecond?
Use the reverse factor: 1 cup per days equals 6.023395e-10 imperial gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) 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 gallon per millisecond to cup per days conversion exact?
Yes. Both imperial gallon per millisecond and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 1660193177 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.
