'k', 'M', and 'G' are SI (unit) prefixes or metric prefixes,

We could use a real name to attach to the commit ...

Sorry, see below.

Umm, no, the letters are used as postfixes, not prefixes; this is wrong.

As a physicist, I strongly disagree.

As a guy involved in metrology I concur with Marcus, the fact we omit b is just a convenience.
