Beaufort Wind Scale

Converts a Beaufort force number into an approximate wind speed.

Formula

v = 0.836\,B^{3/2}

Variables

vWind speed (m/s)

BBeaufort number (0–12)

Example

Force 8 gale: v ≈ 0.836×8^1.5 ≈ 18.9 m/s

Did You Know?

Admiral Beaufort devised his scale in 1805 to standardise ship logbook wind reports.
