Meaning & usage
Micro (µ) is a unit, technical mark or specialized text sign.
Use it with the correct measured value or legal context; a trademark or copyright symbol does not establish rights by itself.
U+00B5 identifies this exact micro form; copying the character preserves its Unicode identity, while its appearance depends on the font or emoji renderer.
micro occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with µ in search, filenames or text processing.
How to type micro
- Windows
- Use Win + . for the emoji and symbol panel, or Character Map for supported fonts. In Microsoft Word, enter each hexadecimal code (B5) 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 micro. 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 B5, then Enter. Enter each code point separately for sequences. Other desktops or apps may require their character picker.
- iPhone & Android
- Look for micro 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.
