Speed Converter

Convert speed between meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), knots, and feet per second (ft/s).

How Speed Conversion Works

Speed measures how far an object travels in a given amount of time. Since different systems use different units, conversions are based on standardized relationships between these units.

Speed Conversion Factors (Base: m/s)

1 m/s   = 3.6 km/h  
1 m/s   = 2.23694 mph  
1 m/s   = 1.94384 knots  
1 m/s   = 3.28084 ft/s

Common Uses

  • Running and treadmill pace conversions
  • Vehicle and speedometer readings
  • Aviation and maritime speed (knots)
  • Physics and scientific calculations
