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.

- Number representations (bases, Roman numerals, scientific notation, prime factorization, etc.)
- Bytes
- Text
- Time zones
- Dates
- Measurements
- Phonetics (includes IPA–X-SAMPA conversion)

- 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)
