A knot is a unit of speed commonly used in marine and aviation contexts. One knot is equal to one nautical mile per hour.
The knot is the standard unit of speed in aviation, sailing, and marine weather, equal to one nautical mile per hour. Because a nautical mile is based on the Earth's geometry, knots are convenient for navigation but unfamiliar to most people reading a general forecast, which is why converting to mph or km/h is so often needed. Marine and aviation warnings, wind reports, and boating forecasts almost always use knots, so being able to translate them into everyday units quickly is genuinely useful. This tool converts knots to mph and shows km/h alongside.
To convert knots to miles per hour, multiply by 1.151. This tool helps translate marine and aviation wind speeds into more commonly understood land-based units.
