Meaning & usage
Superscript 2 (²) places a character above or below the normal text baseline.
It is useful for powers, formulas and compact labels, but Unicode raised letters are not a complete replacement for formatted mathematics.
U+00B2 identifies this exact superscript 2 form; copying the character preserves its Unicode identity, while its appearance depends on the font or emoji renderer.
superscript 2 occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with ² in search, filenames or text processing.
How to type superscript 2
- Windows
- Use Win + . for the emoji and symbol panel, or Character Map for supported fonts. In Microsoft Word, enter each hexadecimal code (B2) and press Alt + X. There is no universal decimal Alt code for this character; legacy Alt codes depend on the code page.
- Mac
- Open Character Viewer with Control + Command + Space and search for superscript 2. With the Unicode Hex Input keyboard enabled, hold Option and enter the UTF-16 units shown above. Standard Option shortcuts do not cover every Unicode symbol.
- Linux
- In compatible GTK applications, press Ctrl + Shift + U, enter B2, then Enter. Enter each code point separately for sequences. Other desktops or apps may require their character picker.
- iPhone & Android
- Look for superscript 2 in your emoji keyboard if available, or copy it here and paste. Save frequently used symbols as a text replacement or keyboard shortcut; availability varies by keyboard.
