About Converting Imperial gallon per Seconds to Cup per Seconds
Imperial gallon per Seconds and Cup 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
cup per seconds = imperial gallon per seconds × 19.2151988081
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 seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cup per seconds factor of 19.2151988081.
Simple example
1 imp gal/s × 19.21519881 = 19.21519881 cup/s
1 imperial gallon per seconds = 19.21519881 cup per seconds.
Real-world example
60 imp gal/s × 19.21519881 = 1,152.911928 cup/s
60 imperial gallon per seconds = 1,152.911928 cup per seconds.

Multiply the imperial gallon per seconds value by 19.21519881. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to imperial gallon per seconds?
Use the reverse factor: 1 cup per seconds equals 0.0520421365 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 seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the imperial gallon per seconds to cup per seconds conversion exact?
Yes. Both imperial gallon per seconds and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 19.21519881 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.
