Abstract: The determination of the Avogadro Constant from selected silicon crystals is described. The density molar mass and lattice spacing of the 2 crystals were measured at NMIJ, PTB, IRMM, IMGC and NIST. When all date are combined, it leads to the Avogadro Constant of 6.022 135 3 (21) 10^23 mol^-1.
