About Converting Cups per Millisecond to Imperial gallon per Seconds
Cup per Millisecond and Imperial gallon per Seconds 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 seconds = cups per millisecond × 52.0421365393
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 seconds equals 0.00454609 base units, so dividing one by the other gives the direct cup per millisecond-to-imperial gallon per seconds factor of 52.0421365393.
Simple example
1 cup/ms × 52.04213654 = 52.04213654 imp gal/s
1 cup per millisecond = 52.04213654 imperial gallon per seconds.
Real-world example
60 cup/ms × 52.04213654 = 3,122.528192 imp gal/s
60 cups per millisecond = 3,122.528192 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cup per millisecond?
1 cup per millisecond equals 52.04213654 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per millisecond to imperial gallon per seconds?
Multiply the cup per millisecond value by 52.04213654. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cup per millisecond?
Use the reverse factor: 1 imperial gallon per seconds equals 0.0192151988 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 seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cup per millisecond to imperial gallon per seconds conversion exact?
Yes. Both cup per millisecond and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 52.04213654 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.
