Abstract :
Summary form only given. The author discusses the possibility of certain fundamental physical constants replacing the current unit of mass in the International System of Units. These constants include the Rydberg, fine-structure, Josephson, and von Klitzing constants, the atomic mass of the proton, and the proton-electron mass ratio.<>
