About Converting Imperial gallon per Seconds to Cups per Millisecond
Imperial gallon per Seconds 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 gallon per seconds × 0.0192151988081
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 cup per millisecond equals 0.2365882365 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cup per millisecond factor of 0.0192151988081.
Simple example
1 imp gal/s × 0.01921519881 = 0.0192151988 cup/ms
1 imperial gallon per seconds = 0.0192151988 cups per millisecond.
Real-world example
60 imp gal/s × 0.01921519881 = 1.152911928 cup/ms
60 imperial gallon per seconds = 1.152911928 cups per millisecond.

Frequently asked questions
How many cups per millisecond are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 0.0192151988 cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cup per millisecond?
Multiply the imperial gallon per seconds value by 0.01921519881. The converter above does this instantly to whatever precision you set.
How do I convert cup per millisecond back to imperial gallon per seconds?
Use the reverse factor: 1 cup per millisecond equals 52.04213654 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) 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 gallon per seconds to cup per millisecond conversion exact?
Yes. Both imperial gallon per seconds and cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.01921519881 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.
