[Tex/LaTex] Expressing capital M for molar in siunitx package

siunitx

The following code isn't valid but conveys my intention:

\SI{}{\micro\molar}

as in micro followed by a big M. I don't want to use the explicit form of micro moles per L raised to the negative one in this case.

Joseph Wright just answered a similar question on comp.text.tex:

Take a look at the section 'loading additional units' in the manual. In version 1, I did include \molar and \Molar, but tightened up on sticking to SI units (almost) exclusively for version 2. The suggested definitions are

\DeclareSIUnit\molar{\mole\per\cubic\deci\metre}
\DeclareSIUnit\Molar{\textsc{m}}
