=== तापमान और अंतराल ===
<!-- Because the kelvin is an individual unit of measure, it is particularly well-suited for expressing ''temperature intervals:'' differences between temperatures or their uncertainties (e.g., “Agar exhibited a melting point hysteresis of 25 kelvins.” and “The uncertainty was 10 millikelvins.”). Of course, the kelvin is also used to express specific temperatures along its scale (e.g. “[[Gallium]] melts at 302.9146 kelvin”).

One disadvantage of the kelvin is that intervals ''and'' specific temperatures on the Kelvin scale use exactly the same symbol (e.g., “Agar exhibited a melting point hysteresis of 25 K,” and “The triple point of hydrogen is 13.8033 K”). -->

<!-- ===Formatting and typestyle for the K symbol===
The kelvin symbol is always a [[Roman type|roman]], [[Italic type|non-italic]] capital K. In the SI naming convention, all symbols named after a person are capitalized; in the case of the kelvin, capitalizing also distinguishes the symbol from the SI prefix “kilo”, which has the lowercase k as its symbol. The admonition against italicizing the symbol K applies to all SI unit symbols; only symbols for variables and constants (e.g. ''P'' = pressure, and ''c'' = 299,792,458 m/s) are italicized in scientific and engineering papers. As with most other SI unit symbols (angle symbols, e.g. 45° 3′ 4″, are the exception) there is a space between the numeric value and the kelvin symbol (e.g. “99.987 K”).<ref name=nist>{{cite web | title=SI Unit rules and style conventions | url=http://physics.nist.gov/cuu/Units/checklist.html | publisher=National Institute of Standards and Technology | date=September 2004 | accessdate=2008-02-06}}</ref><ref name=sib533>{{cite web | title=Rules and style conventions for expressing values of quantities | work=SI Brochure, 8th edition | pages=Section 5.3.3 | url=http://www.bipm.org/en/si/si_brochure/chapter5/5-3-2.html#5-3-3 | publisher=Bureau International des Poids et Mesures | date=1967 | accessdate=2008-02-06}}</ref>

===The special Unicode kelvin character===
[[Unicode]] provides a [[Unicode compatibility characters|compatibility character]] for the kelvin at U+212A (decimal 8490), for compatibility with CJK encodings that provide such a character (as such, in most fonts the width is the same as for [[fullwidth]] characters). Below in maroon text is the kelvin character followed immediately by a simple uppercase K:

:<span class="Unicode" style="color:#721F01;font-size:bigger">K K</span>

When viewed on computers that properly support Unicode, the above line may be similar to the line below (size may vary): -->

:[[चित्र:Kelvin symbol plus K.svg|23px]]
<!-- 
The canonical decomposition of this character is U+004B (uppercase K), so some browsers may simply display a "K" in its place due to [[Unicode normalization]].-->
