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.


Knot (Uk)

A knot (kt) is a unit of speed equal to one nautical mile per hour, commonly used in maritime and aviation contexts.

History/Origin

The knot originated in the 17th century as a measure for sailors to estimate their speed using a device called a chip log, which involved counting the number of knots that passed through a sailor's hands over a specific time interval. It became standardized as a nautical speed unit over time.

Current Use

Today, the knot is primarily used in maritime and aviation industries worldwide to measure vessel and aircraft speeds, maintaining its historical significance and practical application.
