Speed Units

Convert between Kilometers per hour, Miles per hour, Knots, and more.

Available Converters

Kmph to Mph

Convert Kilometers per hour (km/h) to Miles per hour (mph).

Mph to Kmph

Reverse conversion tool to calculate Kilometers per hour from Miles per hour.

Speed Units | All you need to know

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.

Common Speed Units

  • Km/h (Kilometers per hour)The standard unit for speed limits in most of the world.
  • Mph (Miles per hour)The standard unit for speed limits in the US and UK.
  • m/s (Meters per second)The SI unit of speed and velocity.
  • Knot (kn)A unit of speed used in aviation and maritime contexts. 1 nautical mile per hour.
  • MachSpeed relative to the speed of sound.

Converting Speed

Speed conversions allow you to compare velocities across different systems.

1 km/h ≈ 0.621371 mph

1 mph = 1.60934 km/h

1 m/s = 3.6 km/h

1 knot ≈ 1.852 km/h

Why is Speed Conversion Important?

Drivers traveling between countries with different measurement systems (e.g., Canada to USA) need to understand speed limits. Aviation and maritime industries use specific units like knots, requiring conversion for general understanding.
