About Knot (kn)
A unit of speed equal to one nautical mile per hour (about 0.5144 m/s or 1.852 km/h). Knots are the international standard for maritime shipping, recreational boating, weather (wind-speed reports in meteorology), and aviation — pilots worldwide quote airspeed, wind speed, and ground speed in knots because the math of navigation (a nautical mile = one minute of latitude) lines up cleanly with chart work. "Knot" comes from the historical log-line method of measuring ship speed using knotted rope.
About Mile per Hour (mph)
An imperial unit of speed used for road traffic, aviation airspeed (in the US), and wind speed in the US and UK. Standard US highway speed limits are 55–80 mph; urban limits are 25–45 mph. Converting mph to km/h (multiply by 1.609) is one of the most frequent speed conversions online, particularly for international travelers and drivers crossing US/Canadian or UK/European borders where signage switches units.
