Very close, except for the size of the quads.

Correct.
Knuth says
The macros \enskip, \quad, and \qquad provide spaces that are
legitimate breakpoints within a paragraph; \enspace, \thinspace, and
\negthinspace produce space that cannot cause a break...
\def\enskip{\hskip.5em\relax}
\def\quad{\hskip1em\relax} \def\qquad{\hskip2em\relax}
\def\enspace{\kern.5em }
\def\thinspace{\kern .16667em }...
The TeXBook, p. 352.
Roughly, then
\enskip ~ en space
\quad ~ em space
\qquad ~ 2em space
\enspace ~ en kern
\thinspace ~ thin kern
Not the most enlightening choice of names, but we have that problem as well.
