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.
Mile/hour
The mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom to measure the speed of vehicles. It indicates the number of miles traveled in one hour. This unit is prevalent in transportation and is used on road signs and vehicle speedometers in countries where the imperial system is used.
