To convert kilometers per hour (km/h) to meters per second (m/s), you need to use the conversion factor that relates the two units. The conversion factor is:
1 km/h = 0.2778 m/s
To convert 1 km/h to m/s, you multiply 1 by the conversion factor:
1 km/h * 0.2778 m/s = 0.2778 m/s
Therefore, 1 kilometer per hour is equal to approximately 0.2778 meters per second.
