U+00B3 "³" Superscript Three Unicode Character

U+00B3 "³" Superscript Three is a typographic symbol representing the digit three written in a smaller, raised format, used primarily in mathematical, scientific, and technical contexts. It most commonly denotes the operation of cubing a number or unit, such as in cubic meters (m³) or exponentiation like 2³ equals 8. Originating from the ISO 8859 1 Latin 1 character set for easy encoding, this character serves as a concise alternative to the full superscript formatting required in plain text environments. While it is distinct from the superscript glyph manually created in word processors, its inclusion in Unicode ensures consistent representation across digital platforms and fonts.
