Wind Speed Converter Wind Speed Converter This converter requires the use of Javascript enabled and capable browsers. This script creates a wind speed converter that can convert six different speed units at one time. Type the wind velocity you want to convert into the know speed value box. Click on the corresponding Convert button and read the results in the other fields. Use the Clear Values button to start over. The Beaufort unit is given for a range of wind velocities, which are measured at an altitude of 10 m above plain ground in open surroundings. It is a calculated value and other values cannot be calculated from it. Generally, all wind speeds faster than 11 Beaufort are grouped together to 12 Beaufort. The scale is most often used for marine use; with the designated measurements divided into 12 values, as we have in our generally accepted Beaufort Scale Chart. Our calculator breaks the higher end winds down further and into a total of 15 designations (preferred by the National Weather Service); however, in either case, the higher the Beaufort value, the stronger the winds. All calculated results have been rounded to 5 significant digits.
