"केल्विन": अवतरणों में अंतर

<!-- In science and in engineering, the Celsius scale and the kelvin are often used simultaneously in the same article (e.g. “…its measured value was 0.01023 °C with an uncertainty of 70 µK…”). This practice is permissible because the degree Celsius is a special name for the kelvin for use in expressing Celsius temperatures and the magnitude of the degree Celsius is exactly equal to that of the kelvin.<ref name=sib222>{{cite web | title=Units with special names and symbols; units that incorporate special names and symbols | work=SI Brochure, 8th edition | pages=Section 2.2.2, Table 3 | url=http://www.bipm.org/en/si/si_brochure/chapter2/2-2/table3.html | publisher=Bureau International des Poids et Mesures | date=2006 | accessdate=2008-02-06}}</ref> Notwithstanding the official endorsement provided by Resolution 3 of the 13th CGPM, states “a temperature interval may also be expressed in degrees Celsius,” the practice of simultaneously using both “°C” and “K” remains widespread throughout the scientific world as the use of [[SI prefix#List of SI prefixes|SI prefixed]] forms of the degree Celsius (such as “µ°C” or “microdegrees Celsius”) to express a temperature interval has not been well-adopted.<ref name=res313>{{cite web | title=Resolution 3: SI unit of thermodynamic temperature (kelvin) | work=Resolutions of the 13th CGPM | url=http://www.bipm.fr/en/CGPM/db/13/3/ | publisher=Bureau International des Poids et Mesures | date=1967 | accessdate=2008-02-06}}</ref> -->

 

<!-- The kelvin is often used in the measure of the [[color temperature]]of light sources. Color temperature is based upon the principle that a [[black body|black body radiator]] emits light whose color depends on the temperature of the radiator. Black bodies with temperatures below about 4000 K appear reddish whereas those above about 7500 K appear bluish. Color temperature is important in the fields of image projection and [[photography]] where a color temperature of approximately 5500 K is required to match “daylight” film emulsions. In [[astronomy]], the [[stellar classification]] of stars and their place on the [[Hertzsprung-Russell diagram]] are based, in part, upon their surface temperature, known as [[effective temperature]]. The photosphere of the Sun, for instance, has an effective temperature of 5777 K. -->
