Wind speed on the 1946 Beaufort scale is based on the empirical relationship: [7] v = 0.836 B3/2 m/s. v = 1.625 B3/2 knots (. = 13 8 B 3 {\displaystyle = {\frac {13} {8}} {\sqrt {B^ {3}}}} ) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number. See more The Beaufort scale /ˈboʊfərt/ is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. See more The Beaufort scale is not an exact nor an objective scale; it was based on visual and subjective observation of a ship and of the sea. The corresponding integral wind speeds were determined later, but the values in different units were never made equivalent.
