About Kilometer per Hour and Meter per Second

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
METRIC UNIT

Meter per Second

m/s
Definition
The SI unit of speed. Meters traveled per second. Used in science and engineering.
SI / Standard Information
SI-derived unit (m/s). The fundamental unit of velocity in physics. 1 m/s = 3.6 km/h.
Approximate Comparison
1 m/s is about 3.6 km/h or 2.24 mph — a gentle walking pace.
Practical Applications
  • Physics and engineering calculations
  • Wind speed measurement for meteorology
  • Conveyor belt and machinery speed
  • Projectile and ballistic analysis
Real-World Examples
  • A gentle breeze is about 3-5 m/s
  • A sprinter Usain Bolt reached about 10.44 m/s
  • The speed of sound at sea level is about 343 m/s
