A knot is a unit of speed equal to one nautical mile per hour (1.852 km/h), traditionally used in maritime navigation, aviation, and meteorology to denote wind speed.

Common Knot Conversions

  • 1 knot = 1.852 km/h — exact value by definition.
  • 1 knot ≈ 1.151 mph — multiply by 1.151 to convert to miles per hour.
  • 1 knot ≈ 0.514 m/s — multiply by 0.514 to convert to meters per second.
  • 1 knot ≈ 0.00150 Mach — at sea level and 20 °C.

Unlike km/h and mph, the knot is not used in ground transportation — it is strictly a maritime and aviation unit.
