In former times, before wind measuring equipment was available,
the Beaufort Scale was the only device available to determine the wind force.
The scale was invented in the year 1805 by Sir Francis Beaufort and officially adopted in 1838.
Sir Francis Beaufort sailed for many years in the British Royal Navy as a Commander.
The first Beaufort Scale was originally related to tall ships and their sails. Later on it was modified to imply the effects of wind on land and sea.
