Copy the diameter symbol
The Ø symbol (or its lowercase variant ø) is mainly used in technical and engineering drawings to denote the diameter of circular objects such as holes, pipes, or shafts. It is not about the mathematical average of numbers, but about the geometric diameter of a circle.
However, when talking about the mathematical average of numbers (including grade averages), there is no definitive symbol. In mathematics, x with a line above it x̅ is often used, which denotes the arithmetic mean (average value) of a set of numbers.
There are two versions of this symbol:
- Uppercase Ø - used in official technical drawings and documentation
- Lowercase ø - more common in informal communication and texts
Depending on your operating system, use one of the following methods:
- Windows: Press Alt + 0216 (Ø) or Alt + 0248 (ø) on the numeric keypad
- macOS: Press Option + Shift + O for Ø
- macOS: Press Option + O for ø
- Linux: Press Ctrl + Shift + U, type 00D8 (Ø) or 00F8 (ø) and press Enter
On mobile devices, typing the Ø symbol is simpler:
- iOS: Hold the letter O to display variants, including Ø and ø
- Android: Hold the letter O to see options, including Ø and ø
In most text editing programs, you can insert the Ø symbol:
- Microsoft Word: Insert → Symbol → Select Ø or ø
- Google Docs: Insert → Special characters → Search 'diameter'
- Excel: Use function =CHAR(216) for Ø or =CHAR(248) for ø
In HTML, you can insert the Ø symbol in several ways:
Simply type the Ø character directly in the HTML code:
<span>Średnica: Ø</span>Use the named HTML entity:
<span>Średnica: Ø</span>Displays as: Średnica: Ø
Use the numeric HTML entity:
<span>Średnica: Ø</span>Also displays as: Średnica: Ø
You can also use the Unicode character directly in UTF-8:
Średnica: ØMake sure your HTML document has UTF-8 encoding.
The Ø symbol is a versatile symbol used mainly in technical contexts to denote diameter. Although there are many ways to type it, the most convenient is often holding the letter O on a phone or using a keyboard shortcut on a computer. In HTML, the named entity method is preferred for code readability.
