Speed Converter

Comprehensive Speed Converter

Speed is a key parameter in physics, engineering, and everyday life—whether you’re calculating the velocity of a vehicle, analyzing fluid dynamics, or studying astronomical phenomena. Our Speed Converter tool enables you to effortlessly convert between a wide range of speed units, from everyday units like kilometers per hour and miles per hour to specialized units such as knots and even the speed of light.

What Units Are Covered?

Our converter supports a comprehensive list of speed units with conversion factors relative to the base unit, meter per second (m/s). Some of the key units include:

• Metric Units:

  • Meter/second [m/s] – The SI base unit for speed.

  • Kilometer/hour [km/h] – Commonly used for road speeds.

  • Kilometer/minute [km/min] and Kilometer/second [km/s] – For high-speed applications.

• Imperial Units:

  • Mile/hour [mi/h] – Widely used in countries like the United States.

  • Mile/minute [mi/min] and Mile/second [mi/s] – For extremely high speeds.

  • Foot/second [ft/s] – Often used in engineering calculations.

• Subdivisions and Small Units:

  • Meter/hour [m/h], Meter/minute [m/min], Centimeter/second [cm/s], Millimeter/second [mm/s], etc.

  • Units such as Centimeter/hour [cm/h] and Millimeter/minute [mm/min] for precise measurements.

• Nautical and Special Units:

  • Knot [kt, kn] and Knot (UK) [kt (UK)] – Standard in marine and aviation.

  • Astronomical and Cosmic Speeds:
    Units like the Velocity of light in vacuum, Cosmic velocity variants, Earth’s velocity, and even speeds related to the Velocity of sound in water and Mach numbers.
