Mach (20°C, 1 atm)
Ma
Definition
Mach at 20°C and 1 atmosphere is the speed of sound in air under these specific conditions, approximately 343.6 meters per second. It is used as a reference for measuring high speeds, particularly in aviation and aerospace applications.
History/Origin
The Mach number was named after Austrian physicist Ernst Mach and became the standard for measuring high speeds in aviation. It represents the ratio of an object's speed to the speed of sound in the surrounding medium.
Current Use
Mach is used in aviation for measuring aircraft speeds, in aerospace engineering for high-speed vehicle design, and in various applications involving high-speed motion. It is particularly important for supersonic and hypersonic flight.

Knot
kt
Definition
The knot is a unit of speed used in maritime and aviation contexts, representing one nautical mile per hour. It is the standard unit for measuring ship speeds, aircraft speeds, and wind speeds in navigation and meteorology worldwide.
History/Origin
The knot has its origins in maritime navigation, where sailors used a rope with knots tied at regular intervals to measure ship speed. The term "knot" comes from this practice, and it became the standard unit for maritime and aviation speeds.
Current Use
The knot is used worldwide in maritime navigation for ship speeds, in aviation for aircraft speeds, in meteorology for wind speeds, and in various navigation applications. It is the standard unit in these fields regardless of the country's measurement system.
