Ah! This is good, not only for font sizes. (And, by the way, I made a mistake in my previous reply ---tiny size is 6pt as Karl Berry writes in said document, not 7pt as I said.)

As to where to look for this data, it is, in a TeXLive distribution, in

/usr/local/texlive/2009/texmf-dist/tex/latex/base

There you can look into bk10.clo, bk11.clo, bk12.clo, size10.clo, size11.clo, and size12.clo. As you might know, the first number is the font size, and the second the baseline skip; so, for example,

\newcommand\tiny{\@setfontsize\tiny\@vipt\@viipt}

means tiny is 6pt in size with 7pt baseline skip (leading).
