Going the other way, if you want to enter the LaTeX variant called MathJax locally (PC and Mac), which is used on math.stackexchange.com (among other other places), try http://www.inkcode.net/qute. I find this very handy for short to moderate length math.
In my weirdness, I like to use qute in split-screen mode, and work out the math as I enter it, never writing anything down. I then make corrections, modify things, move lines around, all in qute. I have developed some techniques for having correct MathJax syntax at almost all times, which I find necessary since qute does not show the result of an incorrect expression.
I find qute very useful for formatting math. Since it is all offline, no connection is needed. After the formatting is correct, I can then push it to the clipboard and paste it into whatever I want (usually math.stackexchange.com).
I recommend qute highly. Again, it is for Windows and Mac OS, not Linux (unfortunately).
@mjcohen weird, I use qute on Linux (Gentoo), there's even an ebuild for it. However it's not hard to built it yourself on linux, actually dead easy. I also use pandoc writing Markdown and compiling to latex → pdf
