How to use
- Enter a wind speed in your unit — km/h, mph, knots or m/s.
- The Beaufort number appears instantly, from 0 to 12.
- Read the plain description, from "calm" up to "hurricane force".
- Compare speeds across units when reading foreign weather reports.
Tips
- The Beaufort scale describes wind effects, so its limits are approximate by nature.
- Sailors and kite flyers usually care about the description, not the number.
- Gusts can be one or two Beaufort numbers higher than the reported average.
- For exact engineering work, use the raw speed, not the Beaufort band.
Note: the Beaufort scale is an observational scale of wind effects — the limits are approximate.
