Yep, it's "Information" now, similar to e.g. "Radioactivity" which had a
more complex name or "Speed" instead of "Velocity".

The quantities in the API are SI ones, listed here on Wikipedia (did they
miss anything?;-)
http://en.wikipedia.org/wiki/International_System_of_Units

There's this BIPM brochure, which now has a nice online version, too:
http://www.bipm.org/en/publications/si-brochure/

We might prefer to quote it (and where appropriate also relevant
sub-sections) rather than pointing to a PDF, especially if that seems
outdated now
