Kilometer/hour
The kilometer per hour (km/h) is a unit of speed commonly used to express the velocity of vehicles, such as cars and trains. It indicates how many kilometers an object travels in one hour. This unit is widely used in everyday life, especially in transportation and speed limit regulations.
Kilometer/second
The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.
