Knots ↔ MPH
Convert knots to miles per hour — used in sailing, aviation, and weather.
What is a Knot?
A knot is a unit of speed equal to one nautical mile per hour. It is used globally in meteorology, maritime navigation, and aviation. Unlike standard miles, nautical miles are based on the Earth's circumference and correspond to one minute of latitude. This makes it the preferred unit for long-distance travel across oceans or through the atmosphere.
Aviation and Sailing
Pilots and sailors rely on knots to measure their speed relative to the air or water. When a plane cruises at 450 knots, it's actually traveling at over 500 mph. For recreational boaters, understanding how knots translate to miles per hour can help in planning trips and understanding weather forecasts that use nautical terminology.
