  • Abstract
    The kilogram, unit of mass, is the last base unit of the International System of Units still defined in terms of a material artifact. A redefinition of the kilogram in terms of an invariant of nature, the Planck constant, is expected in the near future. A review of the present status of the experiments opening the way to this new definition will be presented.
