About Converting Cubic Centimeters per Millisecond to Gallon per Seconds
Cubic Centimeter 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 = cubic centimeters per millisecond × 0.264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic centimeter per millisecond equals 0.001 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic centimeter per millisecond-to-gallon per seconds factor of 0.264172052358.
Simple example
1 cm3/ms × 0.2641720524 = 0.2641720524 gal/s
1 cubic centimeter per millisecond = 0.2641720524 gallon per seconds.
Real-world example
60 cm3/ms × 0.2641720524 = 15.85032314 gal/s
60 cubic centimeters per millisecond = 15.85032314 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic centimeter per millisecond?
1 cubic centimeter per millisecond equals 0.2641720524 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic centimeter per millisecond to gallon per seconds?
Multiply the cubic centimeter per millisecond value by 0.2641720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic centimeter per millisecond?
Use the reverse factor: 1 gallon per seconds equals 3.785411784 cubic centimeters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic centimeter per millisecond?
Cubic Centimeter per Millisecond (cm3/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 cubic centimeter per millisecond to gallon per seconds conversion exact?
Yes. Both cubic centimeter per millisecond and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.2641720524 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.
