Elemental Abundance in Stars - The Curve of Growth
I am studying for my undergraduate Astrophysics module and the lectures notes say that that all abundances are measured relative, in terms of H = 12.00 by mass or number of atoms. Is this correct? I thought it was all based off of Carbon = 12. Am I missing something?

The definition of amu (used for isotope masses) depends on carbon-12, maybe you mixed those two definitions?
