About the superscript three symbol

The superscript three is a small numeral 3 set above the baseline. It is primarily used in mathematical and scientific notation to denote exponentiation, such as in cubic measurements (e.g., m³ for cubic meters) or in algebraic expressions. As a typographic convenience, it allows compact representation of powers without requiring a separate formatting system.

This character belongs to the Latin 1 Supplement block and is categorized as an other number symbol, meaning it is a numeric glyph that does not function as a regular digit in standard writing. It appears in many text environments where superscript formatting is not available, serving as a fallback for representing the exponent three.
