How to Convert Centimeter/Second to Millimeter/Second

To convert from Centimeter/Second (cm/s) to Millimeter/Second (mm/s), multiply the value by 10.

Formula: mm/s = cm/s × 10

Reverse: cm/s = mm/s × 0.1

Step-by-Step Example

Start with your value in Centimeter/Second. For example: 5 cm/s
Multiply by the conversion factor: 5 x 10
The result is: 50 mm/s

About Centimeter/Second

The centimeter/second (cm/s) is a unit of speed and velocity. One centimeter/second equals 0.01 metre per seconds. UnitConvertLab converts it against every other speed unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: speed calculations, engineering and science, education.

About Millimeter/Second

The millimeter/second (mm/s) is a unit of speed and velocity. One millimeter/second equals 0.001 metre per seconds. UnitConvertLab converts it against every other speed unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: speed calculations, engineering and science, education.
