kW

Kw is a two-letter sequence that can refer to several unrelated concepts, depending on context. It does not denote a single, universal idea.

Kilowatt: The kilowatt, written as kW, is the SI unit of power equal to 1,000 watts. It is widely used to express electrical power generation and consumption, motor ratings, and heating or cooling capacities. In technical writing, the correct symbol is kW (lowercase k, uppercase W); the form KW may appear in non-technical contexts but is generally discouraged in precise usage.

Cornish language code: In language tagging and information systems, kw is the ISO 639-1 code for the Cornish language (Kernewek). Cornish is a revived Celtic language associated with Cornwall, United Kingdom, and it appears in linguistic databases, digital resources, and educational materials under this code.

Surname and personal names: Kw also appears as a romanization variant for some East Asian surnames in Cantonese-speaking communities. In practice, it can be a shortened or alternative spelling in family names derived from surnames such as 郭, among others, and may be found in personal naming across Chinese diaspora communities.

Other uses: Depending on field, KW or Kw can serve as an abbreviation for various terms, such as keyword in information retrieval, or as part of organizational acronyms. Because the same two letters can function in multiple domains, the intended meaning is usually clarified by surrounding context or capitalization.
