There is a long history of using just "u" (or "U") as the ASCII-7 representation for "mu" when used as a prefix for 1e-6.

E.g., tv_sec and tv_usec in the "timeval" struct:

It would be somewhat more consistent (and SI-similar) to use "CSECS_IN..."; "centi-" is 1e-2, while "hecta-" is 1e+2.

Both entirely trivial, but they caught my eye.

Also, I wonder if "_PER_" would read more clearly than "_IN_"? I tend towards the former in my code, but I don't know how much of a taste issue that is. As a native [american] english speaker, I sometimes read "x in y" as "x in terms of y", while "x per y" is less ambiguous.
