What is a Knot?
The knot equals exactly one nautical mile (1,852 m) per hour, or approximately 1.852 km/h. It is the international standard for maritime and aviation speeds. The term originates from the 17th-century practice of throwing a chip log — a knotted rope — overboard and counting the knots that passed through the hand in 30 seconds to estimate a ship's speed. A typical commercial airliner cruises at 450–500 knots, and a naval destroyer can reach about 30 knots.
What is a Kilometer per hour?
The kilometer per hour (km/h) is the most widely used unit for road vehicle speeds outside the United States. Equal to 1/3.6 meters per second, it is used for speed limits, railway timetables, and meteorological wind speeds in metric countries. Typical urban speed limits are 50 km/h, while highway limits range from 100 to 130 km/h. One km/h equals approximately 0.621 miles per hour.
