Degree (temperature)

Degree (temperature)
For other uses, see Degree (disambiguation).

The term degree is used in several scales of temperature. The symbol ° is usually used, followed by the initial letter of the unit, for example “°C” for degree(s) Celsius. A degree can be defined as a set change in temperature measured against a given scale, for example, one degree celsius is one hundredth of the temperature change between water melting and water boiling.

Kelvin

Main article: Kelvin

The degree Kelvin (°K) is a former name for the SI unit of temperature on the thermodynamic (absolute) temperature scale. Since 1967 it has been known simply as the kelvin, with symbol K. Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but sometimes the degree Rankine as well.[1]

Comparisons

  • Boiling point of water: 100.0 °C / 212.0 °F
  • Melting point of ice: 0.0 °C / 32.0 °F
  • Typical human body temperature: 37.0 °C / 98.6 °F
  • Room temperature: the 20 - 25 °C / 68 - 77 °F
