4.1 Beaufort Wind Force Scale
If you have selected the use of Beaufort wind speed units, you can use the table below for
reference. The Beaufort scale is based on qualitative wind conditions and how they would affect
a ship’s (frigate) sails (so yes, it is an “old” standard). It is therefore less precise than the other
scales but is still in use in various locales.
