Mile/hour
Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.
History/Origin
The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.
Current Use
Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.
Mile/second
A mile per second (mi/s) is a unit of speed representing the distance of one mile traveled in one second.
History/Origin
The mile per second has been used primarily in scientific contexts, especially in astronomy and physics, to measure extremely high velocities such as those of celestial objects. Its usage has been limited due to the convenience of metric units in scientific measurement.
Current Use
Today, the mile per second is mainly used in scientific research, particularly in astrophysics and space science, to describe high-velocity phenomena like the speed of spacecraft, stars, or other celestial bodies.
