They are not all the degree symbol. I have a PC, so I can only sort it out there: Alt-0176 is the true degree symbol Alt-0186 is the masculine ordinal indicator (there is a superscript a for the feminine) I can't find the third by itself, but some letters (A) take a dicritical ring in some languages.
In some fonts, they may look nearly interchangeable, in other fonts the differences are bigger. ________________________________ From: Andrew Winn <[email protected]> To: U.S. Metric Association <[email protected]> Cc: U.S. Metric Association <[email protected]> Sent: Fri, March 5, 2010 3:51:59 PM Subject: [USMA:46849] Re: degrees symbol I usually just use option-0 (the option key plus the zero key) on my mac. Although, the symbol it produces is slightly bigger than the two you use in your email which is quite perplexing. Whoever knew that there was three different keyboard shortcuts to get a degree symbol? This keyboard shortcut is much easier for me to remember as the degree symbol resembles a tiny zero in superscript.
