Knot
A knot is a unit of speed equal to one nautical mile per hour, commonly used in maritime and aviation contexts.
History/Origin
The knot originated from the practice of measuring a ship's 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 unit of speed in maritime navigation.
Current Use
Today, the knot is primarily used in maritime and aviation industries to express the speed of ships and aircraft, providing a consistent measurement across international waters and airspace.
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.
