The coupling of conformal field theories to 2-d gravity may be studied in the conformal gauge. As an application, the results of Knizhnik, Polyakov and Zamolodchikov for the scaling dimensions of conformal fields are derived in a simple way. Their conjecture for the susceptibility exponent ..gamma.. of strings is proven and extended to arbitrary genus surfaces. The result agrees with exact results from random lattice models.
