What wind speed is Beaufort force 5?

On this site, Beaufort force 5 maps to 9.35 m/s (midpoint of the WMO-style band at 10 m), then converts to knots, mph, etc.

Detailed answer

The Beaufort scale maps observed sea state / wind effects to force numbers 0–12. This converter uses WMO-style mean wind speed ranges at 10 m and maps each force to a representative midpoint in m/s before converting to other units. Force 5 sits in the “fresh breeze” range used in marine forecasts.

Relationship context

Marine forecasts still cite Beaufort force; converting to knots or m/s helps comparison with anemometers and numerical models.
