There really hasn't been any firm explanation of the rating system.

SSS: Strongest Ghouls, Owl is the only known example.

SS: Stronger Ghouls like Shachi and Kaneki.

S: Strong Ghouls like Tsukiyama, Yamori, and Ayato.

A: "Dangerous", but not insanely strong.

B: A lot of Quinque seem to be made from B-scale Ghouls.

C: Weak but worth capture.

S and above apparently has something do to with Ghouls strong enough to fight Special Class Investigators.
