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.
Mach (20°c, 1 Atm)
Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.
History/Origin
Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.
Current Use
Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.
