About Converting Cups per Millisecond to Gallons per Millisecond
Cup per Millisecond and Gallon 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
gallons per millisecond = cups per millisecond × 0.0625
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cup per millisecond-to-gallon per millisecond factor of 0.0625.
Simple example
1 cup/ms × 0.0625 = 0.0625 gal/ms
1 cup per millisecond = 0.0625 gallons per millisecond.
Real-world example
60 cup/ms × 0.0625 = 3.75 gal/ms
60 cups per millisecond = 3.75 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cup per millisecond?
1 cup per millisecond equals 0.0625 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cup per millisecond to gallon per millisecond?
Multiply the cup per millisecond value by 0.0625. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cup per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 16 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 millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the cup per millisecond to gallon per millisecond conversion exact?
Yes. Both cup per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0625 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.
