Type the wind velocity you want to convert into the know speed value box. Beaufort Number or Force: Wind Speed: Description: Effects Land / Sea: mph: km/hr: knots: 0 <1 <1 <1: Calm: Still, calm air, smoke will rise vertically. The Beaufort-scale was never intended to provide accurate windspeed measurements, but rather an estimate based upon the impact of the wind on the environment. 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. The top speed of a tornado -- more violent than any other storm -- is unknown due to the difficulty of successfully employing weather instruments in unpredictable and destructive twisters; the EF5 scale suggests winds in excess of 322 kph (200 mph). It was devised by Irishman Francis Beaufort in 1805, an officer in the British Royal Navy. Water is mirror-like. Direction shown by smoke but not by wind vanes. Click on the corresponding Convert button and read the results in the other fields. Conversion between wind speed measurement units including Beaufort numbers, km/h, m/s, mph, fps. ½-1 ft 0.2 m: Wind felt on face; leaves rustle; ordinary vane moved by wind. Also modern anemometers, used in observations, measure windgusts which can not be reported using the Beaufort-scale. A similar metric, the Saffir-Simpson hurricane wind scale, rates tropical cyclones. Beaufort Wind Scale. 2: 5 kts 6 mph 9 km/h: 4-6 kts 4-7 mph 6-11 km/h: Light: Light breeze: Smooth: Small wavelets, still short but more pronounced, crests have a glassy appearance and do not break. The Beaufort Scale gives us a way of describing measured mean wind speeds (in numbers) with words. Lastly, other Nordic meteorological institutes have used this system for years with satisfactory results. Use the Clear Values button to start over. 1: 1-3 mph: 1-5 kph: 1-3 knots: Light Air: Rising smoke drifts, wind vane is inactive. person_outline Anton schedule 2009-05-23 20:48:55 Beaufort scale was created in 1805 by Sir Francis Beaufort, British admiral and hydrographer. He wanted to create a standard scale, which would allow naval officers to relate sea conditions to a mean wind speed when taking meteorological observations. Small ripples appear on water surface.
