Measurement Units’ Definitions

Kilometers per Hour (km/h)

Kilometers per hour (km/h) is a metric speed measurement unit indicating kilometers traveled in one hour. Symbolized as “km/h”. One kilometer per hour equals approximately 0.539957 knots.

Knots (kn)

Knots (kn) measure speed in nautical and aviation contexts. One knot equals one nautical mile per hour, exactly 1.852 km/h. The symbol is “kn”, used extensively for marine navigation and airspeed.

Conversion Formula

To convert kilometers per hour (km/h) to knots (kn), use the following formula:

knots = km/h ÷ 1.852

Real World Examples

  • City driving speed limit (typical in Europe): 50 km/h = 27.00 kn
  • Highway speed limit (common in Europe): 130 km/h = 70.19 kn
  • Cruising speed of a typical passenger train: 160 km/h = 86.40 kn
  • Average cycling speed (casual ride): 15 km/h = 8.10 kn
  • Speed of a cruise ship (e.g., RMS Queen Mary 2): 56 km/h = 30.24 kn
  • Top speed of a typical city metro train: 80 km/h = 43.19 kn
  • Speed of high-speed ferry (e.g., Seajets Champion Jet 2): 75 km/h = 40.50 kn
  • Typical jogging speed: 9 km/h = 4.86 kn
  • Speed of fastest land animal (cheetah): 100 km/h = 54.00 kn
  • Typical landing speed of commercial aircraft (Airbus A320): 240 km/h = 129.60 kn
