The degree symbol isn't used often enough to be included in a standard keyboard, but that doesn't mean it isn't available. To add special characters like the degree symbol, you have a few options. Many apps, like those in Microsoft Office, include it in the Insert menu. For other apps, you can use the Windows character map. If you are going to use the symbol a lot, it may be worthwhile to memorize its keyboard shortcut so you can type it quickly whenever you need it.
