About these units
Meter per Second (m/s). Meters per second is the SI derived unit of speed, used in physics and engineering. Wind speeds in meteorology and velocity in science are typically quoted in m/s.
Kilometer per Hour (km/h). Kilometers per hour is the standard speed unit for road traffic in metric countries, expressing how many kilometers are covered in one hour. Speed limits and car speedometers use km/h.
