★ Why this converter
A forecast gives you knots, the sign on the trail gives you km/h, and your instrument reads m/s. Wind Speed Converter keeps all of them in front of you at once, so you never guess. The Beaufort description tells you what a number actually feels like — "twigs break off trees" means more than "17 m/s" — and the color-coded danger level warns you the moment conditions turn risky.

The conversion runs entirely on your device. The app is supported by ads.

Keep a fast knot-to-mph and Beaufort calculator in your pocket for the next time the wind picks up.
