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 Mile per hour?
The mile per hour (mph) is the standard speed unit in the United States, United Kingdom, and a few other territories. Equal to approximately 1.609 km/h or 0.447 m/s, it appears on road signs, vehicle speedometers, and weather reports. US interstate highway speed limits are typically 65–75 mph. A commercial airliner cruises at roughly 550–600 mph (880–965 km/h) at altitude.
