The advantages and disadvantages of fixing the values of a number of fundamental physical constants when introducing definitions of the SI units are discussed, in particular a new definition of the unit of mass based on a fixed value of the Avogadro constant....
In addition, its accurate determination is of paramount importancefor a definition of the kilogram in terms of a fundamental constant. We describe a new approach forits determination by ”counting” the atoms in 1 kg single-crystal spheres, which are highly enrichedwith the28 Si isotope. It ...
