"Kilometers per hour" (km/h) is a unit of speed or velocity commonly used in many countries worldwide, particularly those that use the metric system. It represents the distance traveled in kilometers divided by the time taken in hours. Kilometers per hour are frequently used to measure the speed of vehicles, such as cars, bicycles, and trains, as well as the speed of wind and other natural phenomena. This unit provides a convenient measure for understanding and comparing speeds in everyday contexts, especially in transportation and meteorology.
