'''केल्भिन''' (अङ्ग्रेजीमा '''kelvin''', symbol: '''K''') तापक्रम नाप्ने [[एस्.आई.]] ईकाई हो, र सात [[एस्.आई. आधार ईकाई]] मध्येको एक हो। यसलाई दुई तथ्यले ब्याख्या गर्दछ: शुन्य केल्भिन is [[absolute zero]] (when molecular motion stops), and one kelvin is the fraction 1/273२७३.16१६ of the [[thermodynamic temperature]] of the [[triple point]] of [[water]]. The [[Celsius]] temperature scale is now defined in terms of the kelvin, with 0&nbsp;°C corresponding to 273२७३.15१५ kelvins, approximately the [[melting point]] of water under [[ordinary conditions]].
The kelvin is named after the British physicist and engineer [[William Thomson, 1st Baron Kelvin]]; उनका [[barony]] was in turn named after the [[River Kelvin]], which runs through the grounds of the [[University of Glasgow]].

== Typographical conventions ==
The word ''kelvin'' as an SI unit is correctly written with a [[lowercase]] ''k'' (unless at the beginning of a sentence), and is never preceded by the words ''[[degree (temperature)|degree]]'' or ''degrees'', or the symbol °, unlike degrees ''[[Fahrenheit]]'', or degrees ''[[Celsius]]''. This is because the latter are [[adjective]]s, whereas ''kelvin'' is a [[noun]]. It takes the normal plural form by adding an ''s'' in [[English language|English]]: kelvins. When the kelvin was introduced in [[1954]] (10th१०th [[Conférence Générale des Poids et Mesures|General Conference on Weights and Measures (CGPM)]], Resolution 3, CR 79७९), it was the "degree Kelvin", and written '''°K'''; the "degree" was dropped in [[1967]] (13th१३th CGPM, Resolution 3, CR 104१०४).
Note that the symbol for the kelvin unit is always a capital K and never italicised. There is a space between the number and the K, as with all other SI units.
[[Unicode]] includes the "kelvin sign" at U+212A२१२A (in your [[web browser|browser]] it looks like K). However, the "kelvin sign" is [[canonical decomposition|canonically decomposed]] into U+004B००४B, thereby seen as a (preexisting) encoding mistake, and it is better to use U+004B००४B (K) directly.
