About Converting Imperial gallon per Seconds to Metric cup per Seconds
Imperial gallon per Seconds and Metric 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
metric cup per seconds = imperial gallon per seconds × 18.18436
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 metric cup per seconds equals 0.00025 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-metric cup per seconds factor of 18.18436.
Simple example
1 imp gal/s × 18.18436 = 18.18436 metric cup/s
1 imperial gallon per seconds = 18.18436 metric cup per seconds.
Real-world example
60 imp gal/s × 18.18436 = 1,091.0616 metric cup/s
60 imperial gallon per seconds = 1,091.0616 metric cup per seconds.

Multiply the imperial gallon per seconds value by 18.18436. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per seconds back to imperial gallon per seconds?
Use the reverse factor: 1 metric cup per seconds equals 0.0549923121 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 metric cup per seconds?
Metric cup per Seconds (metric cup/s) is a unit of flow rate.
Is the imperial gallon per seconds to metric cup per seconds conversion exact?
Yes. Both imperial gallon per seconds and metric cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 18.18436 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.
