kelvin

== English == === Etymology === Named after Irish-born Scottish physicist William Thomson, Lord Kelvin. === Pronunciation === (UK) IPA(key): /ˈkɛlvɪn/ (US) IPA(key): /ˈkɛlvɪn/, /ˈkɛlvən/, [ˈkʰɛɫvɨn] Rhymes: -ɛlvɪn, -ɛlvən === Noun === kelvin (plural kelvins) In the International System of Units, the base unit of thermodynamic temperature; 1⁄273.16 of the thermodynamic temperature of the triple point of water. Alternative forms: K (symbol); °K (the latter is deprecated) Synonyms: degree Kelvin, degree absolute (both are deprecated) One degree of difference on this scale, as a unit interval. Alternative forms: K (symbol); °K (the latter is deprecated) Synonyms: degree Kelvin, degree absolute (both are deprecated) A measurement of color warmth defined by the temperature kelvin at which an incandescent blackbody would emit a given color. ==== Usage notes ==== As with all SI units, the ordinary English plural kelvins is the recommended one; however in literature it is equally common to treat it as an invariant plural, albeit nonstandard. The term degree Kelvin is nowadays nonstandard and proscribed. One kelvin as a unit interval is the same amount of difference (temperature change) as one degree Celsius as a unit interval. (For example, 0 °C is to 2 °C just as 273.15 K is to 275.15 K.) ==== Derived terms ==== ==== Translations ==== === Further reading === “kelvin”, in OneLook Dictionary Search. == Czech == === Pronunciation === IPA(key): [ˈkɛlvɪn] === Noun === kelvin m inan kelvin (unit of temperature) ==== Declension ==== === Further reading === “kelvin”, in Kartotéka Novočeského lexikálního archivu (in Czech) “kelvin”, in Akademický slovník cizích slov at prirucka.ujc.cas.cz [Academic dictionary of foreign words] (in Czech), 1995 == Finnish == === Etymology === From English Kelvin. === Pronunciation === IPA(key): /ˈkelʋin/, [ˈk̟e̞lʋin] Rhymes: -elʋin Syllabification(key): kel‧vin Hyphenation(key): kel‧vin === Noun === kelvin kelvin (unit of temperature) ==== Declension ==== ==== Derived terms ==== === Further reading === “kelvin”, in Kielitoimiston sanakirja [Dictionary of Contemporary Finnish]‎[1] (in Finnish) (online dictionary, continuously updated), Kotimaisten kielten keskuksen verkkojulkaisuja 35, Helsinki: Kotimaisten kielten tutkimuskeskus (Institute for the Languages of Finland), 2004–, retrieved 2 July 2023 === Anagrams === kilven == French == === Pronunciation === IPA(key): /kɛl.vɛ̃/ === Noun === kelvin m (plural kelvins) a kelvin (unit of temperature) === Further reading === “kelvin”, in Trésor de la langue française informatisé [Digitized Treasury of the French Language], 2012 == Hungarian == === Pronunciation === IPA(key): [ˈkɛlvin] Hyphenation: kel‧vin Rhymes: -in === Noun === kelvin (plural kelvinek) kelvin (base unit of thermodynamic temperature) ==== Declension ==== == Portuguese == === Pronunciation === === Noun === kelvin m (plural kelvins) kelvin (SI temperature unit) === Further reading === “kelvin”, in Dicionário Priberam da Língua Portuguesa (in Portuguese), Lisbon: Priberam, 2008–2026 == Romanian == === Etymology === Borrowed from English kelvin or French kelvin. === Noun === kelvin m (uncountable) a kelvin (unit of temperature) ==== Declension ==== == Serbo-Croatian == === Pronunciation === IPA(key): /kělʋiːn/ Hyphenation: kel‧vin === Noun === kèlvīn m inan (Cyrillic spelling кѐлвӣн) kelvin ==== Declension ==== == Spanish == === Pronunciation === IPA(key): /ˈkelbin/ [ˈkel.β̞ĩn] Rhymes: -elbin Syllabification: kel‧vin === Noun === kelvin m (plural kelvins) kelvin (SI temperature unit) === Further reading === “kelvin”, in Diccionario de la lengua española [Dictionary of the Spanish Language] (in Spanish), online version 23.8.1, Royal Spanish Academy [Spanish: Real Academia Española], 15 December 2025
