Greek Small Letter Gamma γ

The Greek Small Letter Gamma character (γ) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference γ, the decimal numeric character reference γ, or the hexadecimal numeric reference γ. The character is assigned Unicode code point U+03B3 in the Universal Character Set.

Gamma is the third letter of the Greek alphabet, used extensively in physics and mathematics. It represents gamma rays in nuclear physics, the Euler-Mascheroni constant, the Lorentz factor in special relativity, and surface tension in fluid dynamics.

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 Small Letter Gamma character in your HTML documents, the named entity γ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form γ and hexadecimal form γ 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 gamma entity in physics equations (gamma radiation, Lorentz factor γ), mathematics (gamma function Γ), color science (gamma correction), and probability (gamma distribution). It is essential for scientific and engineering web content.
