The original Beaufort scale of wind force is a scale that does not present the actual velocity with which the air moves. It is merely a scale of wind conditions that was used by sailors to categorize the different sailing conditions. Over the years, the use of the scale became very popular. Unfortunately, due to the increasing number of types of sailing ships and eventually the arrival of steam boats, exchanging and comparing wind force information became a problem.
