The degree symbol is a superscript.
I don't know why, but it doesn't always transfer from Word or Word Perfect to the website.
I don’t use MS WORD, but here’s a description:
1. Select the text that you want to format as superscript (superscript: describes text that is slightly higher than other text on a line, such as a footnote reference mark.) or subscript (subscript: Describes text that is slightly lower than other text on a line. Subscripts are often used in scientific formulas.).
2. On the Format menu, click Font, and then click the Font tab.
3. Select the Superscript or Subscript check box.
* Superscript: Press CTRL+SHIFT+=
* Subscript: Press CTRL+=
