Degree (temperature)

Additional recommended knowledge

The term degree is used in several scales of temperature. The symbol ° is usually used, followed by the initial letter(s) of the unit, for example “°C” for degree(s) Celsius.

The most common scales of temperature are:

Other scales of temperature include:

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 Since 1967 it has been known simply as the kelvin, with symbol K. Degree absolute (°A) is obsolete terminology, often referring specifically to the kelvin but sometimes the degree Rankine as well.

Degree symbol

In Unicode, the "degree sign" is U+00B0 (°). The HTML character entity reference for it is °. The Alt codes on Microsoft Windows are Alt+0176 (Unicode) and Alt+248 (ANSI).

Due to a similar appearance in some fonts in print and on computer screens, some other characters may be mistakenly substituted for it: the “masculine ordinal indicator” (U+00BA, º), the “ring above” (U+02DA, ˚), “superscript zero” (U+2070, ⁰), superscript zero proper (0) or superscript letter “o” (o), and the “ring operator” (U+2218, ∘).
