About Converting Cups per Millisecond to Gallon per Seconds
Cup per Millisecond and 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
gallon per seconds = cups per millisecond × 62.5
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 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cup per millisecond-to-gallon per seconds factor of 62.5.
Simple example
1 cup/ms × 62.5 = 62.5 gal/s
1 cup per millisecond = 62.5 gallon per seconds.
Real-world example
60 cup/ms × 62.5 = 3,750 gal/s
60 cups per millisecond = 3,750 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cup per millisecond?
1 cup per millisecond equals 62.5 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per millisecond to gallon per seconds?
Multiply the cup per millisecond value by 62.5. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cup per millisecond?
Use the reverse factor: 1 gallon per seconds equals 0.016 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 gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cup per millisecond to gallon per seconds conversion exact?
Yes. Both cup per millisecond and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 62.5 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.
