Convert any wind speed between m/s, km/h, mph, knots, and ft/s; get the Beaufort force (0 Calm — 12 Hurricane) with the WMO description, sea state, and what it looks like on land.
Beaufort numbers are defined by the WMO at 10 m above ground over open terrain. Boundaries are upper-inclusive — e.g. Force 5 ends at 24 mph; 25 mph is Force 6.
