About Kilometer per Hour and Knot

Detailed information about both units of measurement.

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
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
