Speed
Convert between KPH, MPH, knots, Mach and metres per second
Every converter here works in both directions and shows a table of common values, so you can read off 60 knots in km/h or Mach 2 in km/h without typing anything.
- KPH ↔ MPH — road speeds and speed limits.
- Knots ↔ KPH — aviation, sailing and wind speeds (1 knot = 1.852 km/h).
- Mach ↔ KPH — supersonic speeds as multiples of the speed of sound.
- m/s ↔ KPH — physics and engineering.
KPH ↔ MPH
Convert between kilometers per hour and miles per hour. Essential for driving, cycling, and speed comparisons.
Open ToolMeters/Second ↔ KPH
Convert between meters per second and kilometers per hour. Useful for physics and athletics.
Open ToolKnots ↔ KPH
Convert between knots and kilometers per hour. Essential for aviation and maritime navigation.
Open ToolMach ↔ KPH
Convert between Mach number and kilometers per hour. For aviation and supersonic speeds.
