How to Convert Kilometer/Hour to Meter/Second

To convert from Kilometer/Hour (km/h) to Meter/Second (m/s), multiply the value by 0.2777777778.

Formula: m/s = km/h × 0.2777777778

Reverse: km/h = m/s × 3.6

Step-by-Step Example

Start with your value in Kilometer/Hour. For example: 5 km/h
Multiply by the conversion factor: 5 x 0.2777777778
The result is: 1.388889 m/s

About Kilometer/Hour

Kilometers per hour is the most widely used unit of speed for vehicles in most countries.

Common uses: speed limits, vehicle speed, weather.

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.
