Determine wind force levels using the international Beaufort Wind Scale. Input speeds in m/s, km/h, knots, or mph to map them to scale steps 0 (Calm) through 12 (Hurricane) with corresponding land/sea descriptors.
How to use
- Input your wind speed in m/s, km/h, knots, or mph.
- The values will convert and highlight the corresponding Beaufort scale level instantly.
- Read the physical descriptors for land and sea conditions to evaluate the wind force.
FAQ
- Who created the Beaufort scale?
- It was developed in 1805 by Sir Francis Beaufort, a British Royal Navy officer, to standardize wind descriptions for sailing vessel navigation. It was later adopted globally by the WMO.
- What defines a hurricane-force wind on the Beaufort scale?
- A hurricane corresponds to Level 12 (winds >= 32.7 m/s, 118 km/h, or 64 knots). It causes severe devastation on land and turns the sea surface completely white.
