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.
Millimeter/second
The millimeter per second (mm/s) is a unit of speed representing the number of millimeters an object moves in one second. It is used in precise applications, such as in engineering, materials science, and medical imaging, where small distances and slow movements need to be accurately measured.
