What is the Unicode code point for the cubed symbol?

The cubed symbol (³) is U+00B3, decimal 179, in the Latin-1 Supplement block, the same block as the degree sign and the squared symbol.

What is the Alt code for the cubed symbol on Windows?

Hold Alt and type 0179 on the numeric keypad (Alt+0179). This works in Word, Notepad, and most Windows apps.

How do I type the cubed symbol on a Mac?

Enable the Unicode Hex Input source in Keyboard settings, then hold Option and type 00B3. You can also open Character Viewer (Control+Command+Space) and search "superscript three".

What is the HTML entity for the cubed symbol?

Use the named entity ³, or the numeric entities ³ (decimal) and ³ (hex). All three render as ³.

Is ³ the same as writing x^3?

They look similar but serve different purposes. ³ (U+00B3) is a standalone character used for units like m³ or cm³. Writing x^3 is math notation, typically rendered as a superscript by a typesetting system such as LaTeX rather than typed as this literal character.

Why does my app show a plain 3 instead of a small superscript ³?

Some fonts do not include the Latin-1 Supplement glyph, or the app strips non-ASCII characters on paste. Try pasting as plain text, or switch to a font with full Unicode coverage.
