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.

Conversion

• Numeral systems/Number representations (bases, Roman numerals, scientific notation, prime factorization, etc.)
• Times of day (old, not very good)
• Bytes (in Programming)
• Text (will be on the home page)
• Time zones
• Dates
• Measurements
• Phonetics (includes IPA–X-SAMPA conversion) (in Language stuff)
• Permutations

Calculation

• Vectors
• Functions
• "Everything" formula (a.k.a. Tupper's self-referential formula)
• Latitude/longitude / spherical coordinate distance (only an approximation, because the Earth is only approximately a sphere)
• Kaufman decimals: a generalization of repeated decimals (like 0.3333333…) from Math with Bad Drawings
• Number types (complex numbers, quaternions, various types of infinity... I'll add more later)
• Number of ways of making change
