How to Convert Kilometers per Hour to Meters per Second
Formula
To convert Kilometers per Hour (km/h) to Meters per Second (m/s): multiply by 0.277778
Step-by-Step
- Start with your value in Kilometers per Hour (km/h).
- Multiply by 0.277778 to perform the conversion.
- The result is your value expressed in Meters per Second (m/s).
Conversion Factor
1 km/h = 0.277778 m/s
Reverse Factor
1 m/s = 3.6 km/h
Worked Example
Convert 25 Kilometers per Hour to Meters per Second: 25 km/h = 6.94444 m/s
About Kilometer per Hour (km/h)
A metric unit of speed widely used for road traffic, vehicle speedometers, and transport in every country except the United States and United Kingdom. Also the default unit on GPS devices worldwide and for athletics speed charts in track-and-field. Because 1 km/h = 1/3.6 m/s exactly, conversion between m/s and km/h is trivial — multiply by 3.6 to go from m/s to km/h. Common highway speed limits are 100–130 km/h in most of Europe and Asia.
About Meter per Second (m/s)
The SI base unit of speed, derived from the base units of length (meter) and time (second). Meters per second is the universal unit in physics and engineering calculations — every equation of motion, fluid dynamics, kinematics, and sound propagation assumes m/s unless explicitly stated otherwise. Human walking speed is about 1.4 m/s; highway driving is roughly 25–30 m/s; the speed of sound in air at sea level is 343 m/s.
