Eeww. Consider getting a real code editor (or learn a *NIX standard such as vim or emacs). XCode's builtin editor also would be a step up (presuming you have the OS X development tools installed).

And as a comment to your original program, you might consider using the OS' units program which already has a fairly good knowledge of conversions rather than reinventing the wheel piecemeal yourself. 

$ units kilograms grams
        * 1000
        / 0.001
$ units feet kilometers
        * 0.0003048
        / 3280.8399

(Those two lines are what you multiply the later by to get the former and what you divide the former by to get the later)

Update: Duuur. Strike that, reverse it; as is noted below. Been so long since I've used it I forgot how it works. (At least I remembered it was there . . . :)
