Question: what is wind speed kts?
Answer: The knot is the term for speed used by the aviation and shipping industries. Sometimes abbreviated as KTS, the knot is measured in nautical miles per hour, and should not be confused with speeds given in miles per hour. ... For example, a wind speed of 6.0 KTS is equivalent to a wind speed of 6.0 x 1.15 = 6.9 MPH.
