Beaufort force to knots
Type a value in Bft to get it in kn instantly.
23.88kn
That's about the same as a strong breeze. That pushes with about 92.46 pascals against a flat wall.
Convert the other way: kn to Bft
What it means
How strong is that wind?
Beaufort numbers describe a band of speeds, not one value. The formula used here gives the middle of each band.
The math
How to convert Bft to kn
The Beaufort scale is not linear: v = 0.836 × B^1.5 m/s, so each force covers a wider band of speed than the one below.
Example: 6 Bft = 23.8833 kn.
