International audienceThe "watt balance" project aims at linking the kilogram definition to the Planck constant. The weighing of the mass involved requires a determination of the acceleration g with an uncertainty better than 10 −8. This work aims at determining g with an atomic gravimeter and a dedicated gravimetric site.Le projet « balance du watt » propose de relier la définition du kilogramme à la constante de Planck. La pesée de la masse impliquée nécessite une détermination de l'accélération de la pesanteur g avec une exactitude meilleure que 10^−8. Les travaux résumés dans cet article visent à réaliser cette détermination à l'aide d'un gravimètre atomique et d'un site gravimétrique dédié
