Abstract
Fixing the value of Avogadro's constant, the number of atoms in 12 grams of carbon-12, at exactly 84446886^3 would imply that one gram is the mass of exactly 18x14074481^3 carbon-12 atoms. This new definition of the gram, and thereby also the kilogram, is precise, elegant and unchanging in time, unlike the current 118-year-old artifact kilogram in Paris and the proposed experimental definitions of the kilogram using man-made silicon spheres or the watt balance apparatus.
