5.1 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.
