  An empirical fit to electron-nucleus scattering for $A>2$ is made based on
world data. It is valid for $0<W<3.2$ GeV and $0.2<Q^2<5$ GeV$^2$, and can be
used with caution at lower $Q^2$. The fit is based on previous empirical fits
to electron-proton and electron-neutron scattering, taking into account the
effects of Fermi motion plus a substantial extra contribution that fills in the
dip between the quasi-elastic peak and the $\Delta(1232)$ resonance.
