About Converting Gallon per Seconds to Cubic Centimeters per Millisecond
Gallon per Seconds and Cubic Centimeter 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
cubic centimeters per millisecond = gallon per seconds × 3.785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic centimeter per millisecond equals 0.001 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic centimeter per millisecond factor of 3.785411784.
Simple example
1 gal/s × 3.785411784 = 3.785411784 cm3/ms
1 gallon per seconds = 3.785411784 cubic centimeters per millisecond.
Real-world example
60 gal/s × 3.785411784 = 227.124707 cm3/ms
60 gallon per seconds = 227.124707 cubic centimeters per millisecond.

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