About Converting Cubic Centimeters per Millisecond to Gallons per Millisecond
Cubic Centimeter 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 = cubic centimeters per millisecond × 0.000264172052358
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic centimeter per millisecond-to-gallon per millisecond factor of 0.000264172052358.
Simple example
1 cm3/ms × 0.0002641720524 = 0.0002641721 gal/ms
1 cubic centimeter per millisecond = 0.0002641721 gallons per millisecond.
Real-world example
60 cm3/ms × 0.0002641720524 = 0.0158503231 gal/ms
60 cubic centimeters per millisecond = 0.0158503231 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic centimeter per millisecond?
1 cubic centimeter per millisecond equals 0.0002641721 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic centimeter per millisecond to gallon per millisecond?
Multiply the cubic centimeter per millisecond value by 0.0002641720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic centimeter per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 3,785.411784 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 millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the cubic centimeter per millisecond to gallon per millisecond conversion exact?
Yes. Both cubic centimeter per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0002641720524 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.
