Degree Sign °

The Degree Sign character (°) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference °, the decimal numeric character reference °, or the hexadecimal numeric reference °. The character is assigned Unicode code point U+00B0 in the Universal Character Set.

The degree sign is used to denote temperature, angles, and geographic coordinates. It appears after numbers in temperature readings (72°F, 22°C), angle measurements (90°), and latitude/longitude coordinates (40.7128° N). It is one of the most practically useful symbols for everyday web content.

Symbol entities encompass a wide variety of special characters used in legal disclaimers, intellectual property notices, typographic ornaments, card suit indicators, and miscellaneous notation throughout web content. These characters appear in website footers for copyright notices, product pages for trademark symbols, academic papers for dagger footnote markers, and decorative or gaming contexts for card suits and stars.

When deciding how to encode the Degree Sign character in your HTML documents, the named entity ° is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ° and hexadecimal form ° are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the degree sign for temperatures (72°F, 22°C), angles (45°, 90°, 360°), geographic coordinates (40° 26' N), and academic degree abbreviations in some contexts. It is essential for weather sites, cooking content, navigation applications, and science education pages.
