How to Convert Millimeter/Second to Meter/Second

To convert from Millimeter/Second (mm/s) to Meter/Second (m/s), multiply the value by 0.001.

Formula: m/s = mm/s × 0.001

Reverse: mm/s = m/s × 1,000

Step-by-Step Example

Start with your value in Millimeter/Second. For example: 5 mm/s
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 m/s

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.

About Meter/Second

The meter/second (m/s) is a unit of speed and velocity. One meter/second equals 1 metre per second. 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.
