Greek Pi Symbol ϖ

The Greek Pi Symbol character (ϖ) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ϖ, the decimal numeric character reference ϖ, or the hexadecimal numeric reference ϖ. The character is assigned Unicode code point U+03D6 in the Universal Character Set.

The Greek pi symbol (ϖ) is a variant form of pi that resembles a rounded lowercase omega. It is sometimes called 'varpi' in mathematical typesetting. This variant appears in certain mathematical and scientific notation traditions where it carries a meaning distinct from the standard π.

Greek letter entities are indispensable for scientific papers, engineering documentation, statistical analyses, and mathematical content published on the web. From physics equations using alpha and omega to statistical formulas featuring sigma and mu, these entities allow content authors to include Greek characters reliably without requiring specialized fonts or complex Unicode input methods on the keyboard.

When deciding how to encode the Greek Pi Symbol character in your HTML documents, the named entity ϖ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ϖ and hexadecimal form ϖ 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 pi symbol variant in mathematical notation that follows conventions requiring the rounded pi form. It is less common than the standard π but appears in some specialized mathematics and physics texts. LaTeX users may recognize it as the \varpi command.
