Formula and worked example
kilometres per hour = metres per second × 3.6.
Convert 10 metres per second to kilometres per hour: 10 × 3.6 = 36 km/h.
When you need this
Physics problems, wind speeds in weather data and sprint speeds are often in metres per second. Multiplying by 3.6 gives the more familiar km/h.
