What's to look up? It's c.

Extra credit for those who know how that letter was chosen / for what it stands.
"c" refers to a constant.
Yes, but that's not why 'c' was chosen. See Kolja Kauder's reply for a link that includes an explanation of why it's 'c'. And if you like to keep up with the cutting edge of science (where things are not so settled as to be called "facts"), check out João Magueijo's recent work suggesting that 'c' may not be entirely fixed. A few physicists find it more palatable than inflation. Look for (as in Google) "Variable Speed of Light." Randall Schulz
