About Knot and Kilometer per Hour

Detailed information about both units of measurement.

MARITIME UNIT

Knot

kn
Definition
One nautical mile per hour. The standard speed unit for aviation and maritime navigation worldwide.
SI / Standard Information
Defined as 1.852 km/h or 0.514444 m/s. One knot = one nautical mile per hour. Used globally in aviation and shipping.
Approximate Comparison
A knot is about 1.15 mph or 1.85 km/h — slightly faster than 1 mph.
Practical Applications
  • Aircraft airspeed and groundspeed
  • Maritime vessel navigation
  • Weather wind speed for marine forecasts
  • Sailing and yachting
Real-World Examples
  • A commercial aircraft cruises at about 450-500 knots
  • A typical sailboat travels at 5-10 knots
  • A cruise ship cruising speed is about 20-25 knots
METRIC UNIT

Kilometer per Hour

km/h
Definition
Speed expressed in kilometers traveled per hour. The standard road speed unit worldwide outside the US and UK.
SI / Standard Information
SI-derived unit. Defined as km/h. Used globally for road traffic speed limits, vehicle speedometers, and weather wind speeds.
Approximate Comparison
100 km/h is about 62 mph — highway driving speed in most countries.
Practical Applications
  • Road speed limits worldwide
  • Vehicle speedometer calibration
  • Weather wind speed reporting
  • Athletic pace calculation
Real-World Examples
  • Typical highway speed limits are 100-130 km/h
  • A brisk walking pace is about 5-6 km/h
  • The average running speed is about 10-12 km/h
