The final results of the MACRO experiment on atmospheric neutrino oscillations are presented. The data concern different event topologies with average neutrino energies of ~ 3 and ~ 50 GeV. Multiple Coulomb Scattering of the high energy muons was used to estimate the neutrino energy of each event. The angular distributions, the L/E
ν
distribution, the particle ratios and the absolute fluxes all favour ν
