I believe that in physics journals, "k" is used for kilo to distinguish it from "K" that is used for temperature "degrees Kelvin" (Celsius degrees above absolute zero). (That's the case, I just don't know if that's the reason.) The degree symbol is (was) generally used in typeset stuff, but the convention was developed in the days of the typewriter. But "k" is definitely used for kilo among physicists -- unless there has been some recent "revisionism." I'm not totally up to date in this stuff. Fred Holmes
