- By Rachelle Oblack. Definition: A knot is a unit of measurement for wind speed. In a station model diagram, the knot is generally the standard unit used to indicate wind speed. Mathematically, one knot is equal to approximately 1.1508 statute miles.Formula to convert knots to mph.ormula to convert mph to knots. x mph X .8689762 = knots. If you do not feel like completing the math for the conversion of knots to miles per hour (mph) or kilometers per hour (kph), you can use a free online wind speed calculator to convert the results.

How fast is a knot in mph? Slightly greater than 1.15mph   A knot, or nautical mile (6076 feet), is about 15% longer than a statute mile (5280). So, if you're traveling at a speed of 20 knots in a mo…tor boat, you simply multiply 20 X 1.15 to get 23 mph. To go from mph to knots, multiply mph by about .87 to get knots. One Knot = 1.1507794 MPH (sailors would say 1.15) One MPH = 0. 86897624 Knots (sailors would say 0. A knot, or nautical mile (6076 feet), is about 15% longer than a statute mile (5280). So, if you're traveling at a speed of 20 knots in a motor boat, you simply multiply 20 X 1.15 to get 23 mph. To go from mph to knots, multiply mph by about .87 to get knots.

Beaufort scale Beaufort scale. The wind speeds in different units are not mathematically equivalent; e.g. 12–19 km/h is not equivalent to 8–12 mph, and both are not equivalent to 7–10 knots. The reason is that the Beaufort scale is not an exact nor an objective scale. It was based on visual and subjective observation of a ship and of the sea.

- Winds and wind systems on the Earth. 1  Wind is formed by the flow of air in horizontal directions. In meteorological definitions the coming direction of the wind is called wind direction. 2  1 m/s = 3.60 km/hr = 2.24 mph = 1.94 knot.

How to Convert Knots to MPH A knot is a unit of velocity typically used for boats and aircraft. Miles per hour, on the other hand, measures the speed of cars in the United States. One knot equals a speed of 1 nautical mile per hour, or 6,076 feet per hour. One mile per hour equals 5,280 feet per hour.

Wind speed Wind speed. An anemometer is commonly used to measure wind speed. Wind speed, or wind flow velocity, is a fundamental atmospheric quantity. Wind speed is caused by air moving from high pressure to low pressure, usually due to changes in temperature.

How to Read the Symbols and Colors on Weather Maps Wind speed is indicated by the shorter lines, called barbs, which extend from this longer line. 1  The total wind speed is determined by adding together the different sizes of barbs according to the following winds speeds that each represents: 2  Half barb = 5 knots. 3  Long barb = 10 knots. 4  Pennant (flag) = 50 knots.

- If you want to convert knots to miles per hour, a little background information might make this a little easier because the unit of knots and where it came from isn't exactly common knowledge. A knot is 1/60th of a degree of latitude, or a minute of latitude, so it is actually a minute of distance.

- Figure out how many knots you are traveling, or plan on traveling. The equation to convert knots to miles per hour is: 1 Knot = 1.15077945 mph (1.85200000 km/h). Take your number of knots and multiply it by 1.15. This will give you how fast you are moving in miles per hour.

What is the highest recorded HURRICANE wind speed ever? The most intense storm on record was Typhoon Tip in the northwestern Pacific Ocean in 1979, which reached maximum sustained wind speeds of 165 knots (190 mph, 305 km/h). Tip, however, does not solely hold the record for fastest sustained winds in a cyclone.

- Max Speed in knots =1.4 x (the square root of the waterline length of boat) in feet. Max Speed in knots = 2.43 x (the square root of the waterline length of boat) in metres. Max Speed in km/h = 4.5 x (the square root of the waterline length of boat) in metres. Many owners of light glass fibre cruisers may be surprised when they apply these formulas to their boat. They may well find that their engines are grossly over-powered for river cruising.

Wind Speed and Direction How is Wind Speed and Direction measured? Wind direction is typically reported in degrees, and describes the direction from which the wind emanates. A direction of 0 degrees is due North on a compass, and 180 degrees is due South. A direction of 270 degrees would indicate a wind blowing in from the west.

How far is a knot and why is it called a knot? Report Abuse. A knot is a measurement of speed and not distance. It is a nautical mile per hour. A nautical mile is about 1.15 statute miles or 1 minute of latitude or 1 minute of longitude at the equator.t was initially measured using line with knots tied in along with an hour glass (set in minutes). When the line is thrown over the stern with a small weight attatched the number of knots counted along the line in one minute will tell you the speed of the vessel.
