For additional meanings of "Kelvin", please see Kelvin.

A kelvin (or K) was a unit for temperature, named after Earth physicist and engineer Lord Kelvin. The measurement of 273.15 kelvin was equal to 0 °Celsius, whereas zero kelvin was "absolute zero", or the absence of any thermal motion (heat).

Comparative list of temperatures Edit

20 K equals −253.15 °C.
97 K equals −176.15 °C.
360 K equals 86.85 °C.
500 K equals 226.85 °C.
  • The surface of a Y-class planet was categorized by a surface where the temperature exceeds 500 kelvin, with an extremely turbulent, toxic atmosphere with thermionic radiation. (VOY: "Demon")
  • While conducting an experiment on the star Praxillus, in order to revitalize the Kaelon sun, the results of their initial experiment yielded seventeen hundred percent rise in gamma radiation levels, while the stars' density was measured at eleven hundred grams per cubic centimeter, with a temperature approaching 60,000 degrees kelvin. (TNG: "Half a Life")
  • The external temperature of a Federation shuttlecraft, utilizing metaphasic shielding, could tolerate radiation levels that approach ten thousand rads and temperatures of 1.9 million kelvin, while maintaining an internal cabin temperature of 21 °C. (TNG: "Suspicions")
  • In order to stabilize the core of a star, the temperature had to reach 220 million kelvin. The core density of a star became unstable at 260 million kelvin. (TNG: "Half a Life")

Background informationEdit

Technically, the measurement for kelvin is not preceded by the qualifier "degree", however, the term "degrees kelvin" has been used at various times throughout Star Trek. Geordi La Forge made several references to this term in both "The Child" and "Half a Life" rather than (correctly) simply stating "kelvin". Data, also in "Half a Life", Gideon Seyetik in "Second Sight", Chakotay and Harry Kim in "Alter Ego", the computer voice in "Concerning Flight", Tom Paris in "Demon", and Tuvok in "The Haunting of Deck Twelve" were also guilty of adding the additional qualifier.
