Yes, actually to be strict it would be kibibytes, KiB.

But in 1980/1981 kibibytes didn't exist, all we had was good ol' fat Kilobytes made out of 1024 bytes, and WE LIKED IT.

What's a "kelvinbit"?

Now I want to see someone derive a nice formula that results in a kelvinbit. Offhand, I'd guess something to do with information entropy in temperature sensitive media. (Entropy rather than density as that would be more along the lines of bits/kelvin I'd assume. Or heat output would be kelvins/bit.)

Exactly. ;)
