Detailed Description

The mapping of the Beaufort_ contains values from 0 to 16 (55.6 m/s),
wind speeds greater than 200km/h (55.6 m/s) are given as 17 Bft. Thats why
a value of 17 Bft cannot be converted to SI.

.. hint::

   Negative values or values greater 16 Bft (55.6 m/s) will throw a
   :py:obj:`ValueError`.
