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.

Velocity of Light in Vacuum
c
Definition
The velocity of light in vacuum is the speed at which light travels in a vacuum, approximately 299,792,458 meters per second. It is a fundamental physical constant and the maximum speed at which all energy, matter, and information can travel in the universe.
History/Origin
The velocity of light was first measured by Ole Rømer in 1676, but its exact value was refined over centuries. In 1983, the meter was redefined in terms of the speed of light, making it a fundamental constant of nature with an exact value.
Current Use
The velocity of light is used in physics, astronomy, telecommunications, and various scientific applications. It is fundamental to Einstein's theory of relativity and is used in GPS systems, fiber optic communications, and astronomical calculations.
