Conversion and calculation programs

Is it bad if I can't really summarize what this is in a sentence or so? Basically, this started out as a thing to convert between different number bases, and ASCII-to-binary, and text to morse code, and things like that, and it grew from there in various different directions.

I've been reorganizing my site a bit. Most of this is now on my math page, except where otherwise specified. Bookmarks and direct links should still work.
