The metre and kilogram system served as the basis for the development of the International System of Units, which now serves as the international standard . Because of this, the standards of the CGS system were gradually replaced with metric standards incorporated from the MKS system . The exact list of units used in the MKS system changed over time . It incorporated base units other than the metre, kilogram, and second in addition to derived units . An incomplete list of the base and derived units appears below . Since the MKS system of units never had a governing body to rule on a standard definition, the list of units depended on different conventions at different times . </P>
