What is the Beaufort Scale? Sea like a mirror. Wind felt on face; leaves rustle; ordinary vanes moved by wind. Small wavelets, ripples formed but do not break: A glassy appearance maintained. Raises dust and loose paper; small branches are moved. Small waves - becoming longer; fairly frequent white horses.

Based on the wind speed the wind force can be classified in the Beaufort Scale. Thereby the speeds in the Beaufort Scale are divided into ranges. In the table you will find the ranges in km/h, m/s, knots and mph.

The wind speed measuring unit is meters per second (m/s) and it is the standard unit for velocity and recommended by WMO. Here our wind speed converter quickly converts units like Knots (Kn), Meters per second (m/s), Kilometers per hour (km/h), Mile per hour (mph), Beaufort (Bft).

One of the first scales to estimate wind speeds and the effects was created by Britain's Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations.

The Beaufort Scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. Below is a table showing the Beaufort Scale with speeds in knots, miles per hour and kilometres per hour.

A guide that helps mariners to estimate the wind speed over open water based on the observed wave conditions.

Mar 8, 2019 · This handy cheat sheet will help you estimate the wind speed. Windy enough for you? Our weather forecasts include the wind speed on days when it’s at least 20 km/h.

Oct 19, 2023 · The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. It depicts the force of wind by a series of numbers, typically from 0 to 12. The Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons .

Wind speed on the Beaufort scale can be expressed by the formula: m/s. where v is wind speed and B is Beaufort scale number. The following online calculator converts common wind speed given in common measurement units to Beaufort numbers. sea: Ripples without crests. sea: Small wavelets. Crests of glassy appearance, not breaking.

The Beaufort Wind Scale is named after Sir Francis Beaufort, an admiral in the British Navy. He developed the scale in 1805 in order to estimate wind speed by noting how sails move in the wind. It turned out to be a great help and was later adapted for use on land.
