Units

Common units of land speed include:
  • kilometers per hour, (symbol km/h)
  • miles per hour
    Miles per hour

    The mile per hour is a physical unit of speed, expressing the number of Mile covered per hour.It is currently the Unit of measurement used for speed limits, and speeds, on roads in the United Kingdom and United States....
    , (symbol m/h)
  • meters per second, (symbol ms-1), the SI derived unit
    SI derived unit

    SI derived units are part of the SI system of measurement Units of measurements and are derived from the seven SI base units.Note that while the names of all SI units are in lowercase, the symbols of units named after people are written with an initial capital letter ....
