1 knot = 1.15077945 miles per hour. A knot is a speed of 1 nautical mile per hour. A nautical mile has been defined in slightly varying ways over time. It is based on the distance traveled in moving 1 minute of arc along any meridian. Since the Earth is not a perfect sphere, the exact distance changes from place to place.
A knot, therefore, is not a nautical mile, it is a nautical mile per hour. Thus 1 knot was equivalent to 1 nautical mile per hour; 5 knots were equivalent to 5 nautical miles per hour; etc. The similar sound of knot and naut is entirely coincidental.
