About Knots and Kilometers per Hour
One knot equals exactly 1.852 kilometers per hour. The knot is defined as one nautical mile per hour, where a nautical mile equals 1852 meters. Both ships and aircraft use knots for speed, but weather forecasts and general audiences prefer km/h. A storm with 50-knot winds is blowing at 92.6 km/h — nearly the highway speed limit. Maritime navigation charts show distances in nautical miles and speeds in knots, but coastal weather warnings use km/h for public communication. Sailors and pilots constantly translate between these systems.
