Every way to type the plus-minus sign ±, by platform
WhereHow to type it
Any deviceClick the ± at the top of this page. It goes straight to your clipboard, and you paste it with Ctrl+V on Windows or Cmd+V on a Mac. This is the only method that behaves identically everywhere.
WindowsHold Alt and type 0177 or Alt 241 on the numeric keypad, then release Alt. The number row above the letters does not work for this.
macOSAdd Unicode Hex Input under Keyboard settings, switch to it, then hold Option and type 00B1. Without that input source, open the Character Viewer with Control+Command+Space and search for plus-minus sign.
Linux and ChromeOSPress Ctrl+Shift+U, type 00b1, then press Enter or the space bar. This works in GTK applications and with IBus.
Microsoft WordType 00B1 in the document, then press Alt and X together with the cursor immediately after the last digit. Word replaces the digits with ±.
Google DocsInsert, then Special characters, then paste U+00B1 or type plus-minus sign in the search box. You can also draw the shape in the sketch pad on the right.
Excel and Google SheetsUse the formula UNICHAR(177) in a cell. Copy the cell and paste it as a value if you want the character rather than the formula.
HTMLWrite ±, or the numeric reference ±, or ±. On a page served as UTF-8 the character itself also works.
CSSUse content: "\00B1" inside a ::before or ::after rule. Terminate the escape with a space if the next character is also a hexadecimal digit.
JavaScriptThe escape \u00B1 produces this character inside a string literal, and the same escape is valid in JSON.
