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

Umm, no, the letters are used as postfixes, not prefixes; this is wrong.
As a physicist, I strongly disagree.
They have been originally standardized by the International Bureau
of Weights and Measures as prefixes for units like kg, m, s, etc. and
are commonly known as metric prefixes or SI prefixes. The usage
might be slightly different here, since there is no unit involved,
but they still are the metric prefixes. Never seen or heard the
term "number postfix".
