If you would like to enter the degree symbol (°), try this:
While holding down the ALT key, using the !!NUMERIC!! keypad (not the number
keys across the top of the keyboard), type the sequence 0176.
When you let go of the ALT key, the degree symbol (°) should appear.
Now, if you’re using Outlook or another email client that allows for Word to
be your editor, you can also use:
Insert-->Symbol, then pick “Symbols”.
Make sure “(normal text)” is selected and look for the degree symbol.
Click on the degree symbol and then in the lower right, click on “Insert”,
then click on “Close”.
