Microsoft Word provides a vast array of tools designed to facilitate the creation of professional and academic documents. Among these tools is the Equation Tool, a powerful feature tailored for the insertion of mathematical and scientific symbols, including the Diameter symbol.

This section will guide you through the process of inserting the Diameter symbol in Word using the Equation Tool.

## Type slash O (diameter symbol) with AutoCorrect – MS Word

With this approach, you create your own shortcode for this symbol (i.e. **slash O**). This way, whenever you type the shortcode you assigned, you get the symbol into your Word document.

For instance, you can assign **DSYM** to the symbol. Thus, whenever you type **DSYM** in your document, Microsoft Word will convert it into a diameter symbol using its autocorrect feature.

Without further ado, below are the steps to assign type the diameter symbol in Word using your own shortcuts:

- Click on the Insert tab.
- In the
**Symbols**group, click**Symbol>More Symbols**. The**Symbols**dialog box appears. - Locate the diameter or slash O symbol, then click to select it.
- After selecting it, click on the
**AutoCorrect**button.

The AutoCorrect dialog box appears. In this dialog box, enter the following:

- Replace: DSYM
- With: Ø

- Click
**Add**then click on**OK**.

After performing all the above steps, Microsoft Word will automatically insert the diameter symbol into your document whenever you type DSYM.

However, there some things you should take note of when using the autocorrect approach to type the slash with O sign.

- This is case sensitive. If you assign
**DSYM**using the uppercase letters, it’ll only work for uppercase. Meaning, if you type dsym (in lowercase), MS Word will not recognize it as the code you assign to the slashed O symbol, and hence will not convert it to any symbol. - Another thing to note is that, if there is any text attached before or after the AutoCorrect text, MS Word will not recognize it, unless you type the autocorrect text alone or separate it from any other text. For example, if you XDSYM, it will not convert to the diameter symbol. But if you type X DSYM, it will get converted because there is a space that separates the X from the DSYM.

These are the various ways you may insert or type the diameter symbol (Ø) in Word and other office applications.
