What measurement does "KT" stand for in meteorological terms?

In meteorological terms, "KT" stands for knots, which is a unit of speed commonly used in aviation and maritime contexts. One knot is equivalent to one nautical mile per hour. When reporting wind speeds in METARs, knots provide a standardized measurement that is particularly useful for navigation and flight operations. Other units like kilometers, kelvins, and tons are not applicable in this context; knots specifically convey information about wind speed, which is critical for pilots and meteorologists to understand weather conditions and make informed decisions.
