Actually, the N/C is not the Gaussian dimensions of the E and B fields.
In the Gaussian system the dimension of the E and B fields is
effectively the sqrt(pressure), (i.e. [energy density]^(1/2)) or
sqrt([mass]/[length])/[time].  The units these fields come in, (i.e. the
statvolt/cm and the gauss) are really just the sqrt(g/cm)/s.
