Speed Converter

Convert speed and velocity units between m/s, km/h, mph, knots, ft/s, Mach, and speed of light. Fast and accurate conversion for physics, aviation, automotive, and maritime calculations. Supports both scalar speed and vector velocity inputs.

Conversion Formula

1 m/s = 3.6 km/h = 2.237 mph

Variables:

  • m/sMeters per second
    SI unit(e.g.: 10 m/s)
  • km/hKilometers per hour
    1 m/s = 3.6 km/h(e.g.: 36 km/h)
  • mphMiles per hour
    1 m/s = 2.237 mph(e.g.: 22.37 mph)
