| Description | The Unicode character K, or U+212A, is known as the "Kelvin Sign". It belongs to the "Letterlike Symbols" block and falls under the "Letter, Uppercase" category in the Unicode standard. This character is a graphic representation of the Kelvin unit of thermodynamic temperature, named after physicist Lord Kelvin. The Kelvin unit is used in physical sciences to denote absolute temperature. Unlike degrees Celsius or Fahrenheit, Kelvin is not measured in degrees, so the symbol "K" stands on its own when representing this unit. The specific appearance and usage of this character can depend on the system and application it's being used in. |
