        These are non-standard units of length.


        They vary from person to person.


        Nowadays we use standard unit of length which is same all over the
        world.


        Standard unit of length is metre. [m]


        To measure small lengths we use centimetre. [cm]

        100 centimetres make one metre.


        To measure distance between two places we use kilometre. [km]
