Celsius

The degree Celsius, also known as centigrade (or simply °C) was a unit of temperature based on the metric system.

The Celsius temperature scale was designed so that the freezing point of water was 0 °C, and the boiling point was 100 °C at one Earth atm, which resulted in the zero point of the temperature unit Kelvin (or "absolute zero") being at −273.15 °C.

The body function panels in sickbay measured a patient's body temperature in both Celsius and Fahrenheit. (Star Trek: The Original Series)

The replicators aboard a Federation starship like the USS Enterprise-D were calibrated to the Celsius metric system. (TNG: "The Defector")

Comparative list of temperatures

• −291 °Celsius: The average surface temperature of the planet Theta VIII, with wind speeds of up to 320 meters per second. (TNG: "The Royale")

−291 °Celsius is about eighteen degrees below absolute zero (0 Kelvin), which is a theoretical impossibility, suggesting this was a production mistake and actually meant to be −291 °Fahrenheit (−179 °Celsius).

• −260 °Celsius: The temperature of the accretion disk in a binary star system. (DIS: "The Vulcan Hello")

• −200 °Celsius: The temperature at which invidium became inert. (TNG: "Hollow Pursuits")

• −52 °Celsius: The lower end of the range for the surface temperature on Argeth. (DIS: "Scavengers")

• −40 °Celsius: The temperature that biothermally insulated booties would protect B'Elanna Torres' baby's feet against. (VOY: "Human Error")

• −20 °Celsius: The ambient temperature in the Argala habitat zone, found on board the Nyrian biosphere vessel. (VOY: "Displaced")

• 21 °Celsius: The cabin temperature in the shuttlecraft Justman just before Jo'Bril flew it into the star Vaytan. (TNG: "Suspicions")

• 22 °Celsius: The temperature Spock kept his crew quarters aboard the USS Enterprise set to. (DIS: "Brother")

• 22.2 °Celsius: The temperature detected by initial scans made by the USS Grissom of Sector 1 on the Genesis Planet, indicating also that it was a forested region. (Star Trek III: The Search for Spock)

• 30 °Celsius: The maximum temperature at which liquefied platinum could remain stable. (ENT: "The Xindi")

• 32 °Celsius: The average temperature of Deep Space 9 when the Federation took over the station, indicating the temperature preference of Cardassians. (DS9: "Emissary")

• 37.2 °Celsius: Jean-Luc Picard's body temperature in 2367. (TNG: "Remember Me")

The average body temperature of a Human was 37 °Celsius. In the script for "The Most Toys", after Varria kissed his lips and discovered it to be warm, Data informed her that he had adjustable temperature and chose this degree to approximate Human skin texture.

• 39.1 °Celsius (roughly 102.4 °Fahrenheit): The constant temperature in the internal climate aboard a Borg cube. (Star Trek: First Contact)

• 39.4 °Celsius: The temperature detected by initial scans made by the USS Grissom of Sector 2 on the Genesis Planet, indicating also that it was a desert terrain with minimal vegetation. (Star Trek III: The Search for Spock)

• 45 °Celsius: The higher end of the range for the surface temperature on Argeth. (DIS: "Scavengers")

• 46 °Celsius: The ambient temperature on both the Zooabud and Tanatuva habitat zones, on board the Nyrian biosphere vessel. (VOY: "Displaced")

• 50 °Celsius with a 90% humidity: The conditions on summers in the Rinax marshlands, the hottest it got in the sector surrounding the Talaxian system. Conditions of these marshlands also included vicious lavaflies on Rinax. (VOY: "Macrocosm")

• 55 °Celsius: The average temperature on Lambda Paz, a moon of Pentarus III, classified as barely class M with a desert-like surface. (TNG: "Final Mission")

Readout of Federation habitat

• 76 °Celsius: The ambient temperature of both the Federation and Bourget habitat zones, found on board the Nyrian biosphere vessel. (VOY: "Displaced")

Based on the habitat seen on screen, this temperature figure was likely a production mistake and actually meant to be 76 °Fahrenheit (24 °Celsius), which is a comfortable temperature for Humans.

• 80 °Celsius: The temperature at which ginger tea with honey, Aunt Adele's cure for the common cold was served at. (TNG: "Ensign Ro")

• 150 °Celsius: The exact constant temperature of a pool of thick swirling ooze the Legarans preferred to inhabit in. (TNG: "Sarek")

Variations in temperature

Although not explicitly stated in terms of "degrees of what", the following temperature references were most likely in Celsius.

• −28 degree temperatures were not uncommon in the middle of summer in the Northern Wastes of Andoria. (ENT: "The Aenar")

• 10 – 12 degree drop in temperature on Penthara IV was predicted within the first ten days after the impact of a type C asteroid on the planet. (TNG: "A Matter of Time")

• 12 onkians: The Romulan equivalent to a temperature of drinking water on the cold side of the Celsius system. (TNG: "The Defector")

• 15 degree drop in temperature was requested by the Female Changeling for the rooms on the Dominion Headquarters on Cardassia Prime after she was inflicted with the morphogenic virus. She noted that she didn't "share the Cardassians' love of heat;" nor apparently did Weyoun. (DS9: "Treachery, Faith and the Great River")

• 20 degree increase of temperature occurred on the planet where Dukat and Sisko were stranded in 2374, when the wind died down, much to the liking of Dukat's Cardassian physiology. (DS9: "Waltz")
