5 x + 32) °F. The degree Celsius is the unit of temperature on the Celsius temperature scale[ 1] (originally known as the centigrade scale outside Sweden), [ 2] one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius (symbol: °C) can refer to a ...
The "degree Kelvin" (°K) is a former name and symbol for the SI unit of temperature on the thermodynamic (absolute) temperature scale. [ 1] Since 1967, it has been known simply as the kelvin, with symbol K (without a degree symbol). [ 2][ 3][ 4] Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but ...
The kelvin, symbol K, is the base unit of measurement for temperature in the International System of Units (SI). The Kelvin scale is an absolute temperature scale that starts from 0 K, the lowest possible temperature (absolute zero), then rises by exactly 1 K for each 1 °C.
The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités ), is the modern form of the metric system and the world's most widely used system of measurement. Coordinated by the International Bureau of Weights and Measures (abbreviated BIPM from French: Bureau international des ...
The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.
Degree symbol. The degree symbol or degree sign, °, is a glyph or symbol that is used, among other things, to represent degrees of arc (e.g. in geographic coordinate systems ), hours (in the medical field), degrees of temperature or alcohol proof. The symbol consists of a small superscript circle.

Temperature scales need two values for definition: the point chosen as zero degrees and the magnitudes of the incremental unit of temperature. The Celsius scale (°C) is used for common temperature measurements in most of the world. It is an empirical scale that developed historically, which led to its zero point 0 °C being defined as the ...
