Knots (kn) to Speed of light (c) Conversion
Knots
The knot is a unit of speed equal to exactly one nautical mile per hour (1.852 km/h), the standard unit for maritime and aerial navigation worldwide. Its name derives from the historical practice of measuring ship speed using a knotted rope thrown overboard. Because the nautical mile is tied to the Earth's geometry (one arcminute of latitude), a ship at 1 knot crosses one arcminute of latitude per hour.
Speed of light
The speed of light in a vacuum (c) is exactly 299,792,458 metres per second — a fundamental constant of nature and the ultimate speed limit of the universe. It is the basis of Einstein's Special Theory of Relativity, which establishes that no object with mass can reach or exceed this speed. The definition of the metre itself is anchored to c: one metre is the distance light travels in 1/299,792,458 of a second.
