I figured out he meant b from:

Might as well keep going - oops, maybe not.  I was going to gripe
that SI prefixes greater than unity (K, M, G) are capitalized, and
those less than unity (m, µ, n) were not.  It appears that kilo is
lowercase.  (As are hecta and deka.)

I have a lot of trouble when people who should be writing MB write mb
instead.  Only wrong by 7 decimal orders of magnitude....
