| Abstract: | Research developments in the modification of the SI base units are reviewed. The main methods employed to obtain the natural standard units of mass, electric current and thermodynamic temperature are summarized. Future prospects for using fundamental physical constants to redefine the SI base units and the consequent impact on physics research are discussed. |
