Convert kilometer/hour to meter/second
Please provide values below to convert kilometer/hour [km/h] to meter/second [m/s], or Convert meter/second to kilometer/hour.
1 km/h = 0.2777777778 m/s. To convert kilometer/hour to meter/second, multiply the value by 0.2777777778; to go the other way, divide by it (1 m/s = 3.59999999971 km/h). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 km/h = 0.2777777778 m/s
- 1 m/s = 3.59999999971 km/h
- 10 km/h = 2.777777778 m/s

Kilometer/hour
Kilometer per hour (km/h) is a unit of speed expressing the number of kilometers traveled in one hour.
History/Origin
The km/h unit originated from the metric system, developed in France during the late 18th century, and became widely adopted for measuring speed in transportation and scientific contexts.
Current Use
Km/h is commonly used worldwide to specify vehicle speeds, speed limits, and other applications involving the measurement of speed in everyday life and transportation systems.
Meter/second
The meter per second (m/s) is a unit of speed representing the distance in meters traveled per second.
History/Origin
The meter per second has been used as a standard unit of speed in the International System of Units (SI) since the adoption of the SI system in 1960, based on the meter defined by the speed of light.
Current Use
It is commonly used in physics, engineering, and everyday contexts to measure velocity, such as in transportation, aerodynamics, and scientific research.
