How to Convert Kilometer/Second to Meter/Second

To convert from Kilometer/Second (km/s) to Meter/Second (m/s), multiply the value by 1,000.

Formula: m/s = km/s × 1,000

Reverse: km/s = m/s × 0.001

Step-by-Step Example

Start with your value in Kilometer/Second. For example: 5 km/s
Multiply by the conversion factor: 5 x 1,000
The result is: 5,000 m/s

About Kilometer/Second

The kilometer/second (km/s) is a unit of speed and velocity. One kilometer/second equals 1000 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.
