We report the final measurement of the neutrino oscillation parameters Δm322 and sin2θ23 using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of 23.76×1020 protons on target producing ν and ν beams and 60.75 kt yr exposure to atmospheric neutrinos. The measurement of the disappearance of ν and the appearance of νe events between the Near and Far detectors yields |Δm322|=2.40-0.09+0.08(2.45-0.08+0.07)×10-3 eV2 and sin2θ23=0.43-0.04+0.20(0.42-0.03+0.07) at 68% C.L. for normal (inverted) hierarchy.
