About Converting Metric cups per Millisecond to Imperial gallon per Seconds
Metric 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 = metric cups per millisecond × 54.9923120748
This factor comes from each unit's defined relationship to the category's base unit: 1 metric cup per millisecond equals 0.25 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct metric cup per millisecond-to-imperial gallon per seconds factor of 54.9923120748.
Simple example
1 metric cup/ms × 54.99231207 = 54.99231207 imp gal/s
1 metric cup per millisecond = 54.99231207 imperial gallon per seconds.
Real-world example
60 metric cup/ms × 54.99231207 = 3,299.538724 imp gal/s
60 metric cups per millisecond = 3,299.538724 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 metric cup per millisecond?
1 metric cup per millisecond equals 54.99231207 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert metric cup per millisecond to imperial gallon per seconds?
Multiply the metric cup per millisecond value by 54.99231207. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to metric cup per millisecond?
Use the reverse factor: 1 imperial gallon per seconds equals 0.01818436 metric cups per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric cup per millisecond?
Metric cup per Millisecond (metric 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 metric cup per millisecond to imperial gallon per seconds conversion exact?
Yes. Both metric cup per millisecond and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 54.99231207 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.
