Mile per Second
mi/s
Definition
The mile per second is a unit of speed representing the distance of one statute mile traveled in one second. It is used for measuring extremely high speeds such as those of spacecraft, projectiles, or other high-velocity objects in imperial system countries.
History/Origin
Mile per second was developed for measuring extremely high velocities in physics, astronomy, and aerospace engineering in imperial system countries. It became essential for expressing speeds of spacecraft and other high-velocity objects.
Current Use
Mile per second is used in aerospace engineering for spacecraft velocities, in physics for high-speed particle studies, in astronomy for celestial object speeds, and in military applications in countries using imperial units.

Kilometer per Hour
km/h
Definition
The kilometer per hour is a unit of speed expressing the number of kilometers traveled in one hour. It is commonly used for measuring vehicle speeds, wind speeds, and general transportation velocities in most countries worldwide, except the United States.
History/Origin
Kilometer per hour became widely adopted with the metric system in the 19th century, particularly in Europe and other metric countries. It replaced various regional speed measurements and became the standard for road signs, speedometers, and official speed limits.
Current Use
Kilometer per hour is the primary speed unit for road traffic, aviation, maritime navigation, and weather reporting in metric countries. It is used on speedometers, road signs, weather forecasts, and in transportation planning and safety regulations.
