About Speed Measurements

Speed is the rate at which an object moves, calculated as distance divided by time. Different regions and industries use different speed units.

Common Speed Units
Unit Symbol Definition Common Uses
Miles per hour mph Miles travelled in one hour Road speed limits in US, UK
Kilometres per hour km/h Kilometres travelled in one hour Road speeds in most countries
Metres per second m/s Metres travelled in one second Scientific measurements, physics
Feet per second ft/s Feet travelled in one second Engineering, ballistics
Knots kn Nautical miles per hour Maritime and aviation speeds
Conversion Formulas
  • mph to km/h: multiply by 1.60934
  • km/h to mph: multiply by 0.621371
  • mph to m/s: multiply by 0.44704
  • km/h to m/s: divide by 3.6
  • m/s to km/h: multiply by 3.6
  • mph to knots: multiply by 0.868976
  • knots to mph: multiply by 1.15078
Speed-Related Formulas
  • Time = Distance ÷ Speed
  • Distance = Speed × Time
  • Speed = Distance ÷ Time

Understanding the Speed Calculator
