Kilometers per hour to Beaufort force
Type a value in km/h to get it in Bft instantly.
5.997Bft
That's about the same as a strong breeze. That pushes with about 92.33 pascals against a flat wall.
Convert the other way: Bft to km/h
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 km/h to Bft
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: 44.2 km/h = 5.99711 Bft.
