base u·nits

the fundamental units of length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity in the International System of Units (SI); the names and symbols of the units for these quantities are meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).

This idea had to be abandoned because the path to an SI base unit adopted by the CGPM was too narrow, considering that there are only seven base units.
A good example of an experiment developed to realize the SI base unit of current is the ampere balance [6].
Since the kilogram is the last artifact SI base unit defined in terms of a material artifact, a quantum standard of mass founded on electrical measurements would complete the modern trend of removing all artifacts from the definitions of SI units.
The kilogram is one of the seven SI base units from which all other units can be derived and is the only one which is measured against a physical object - the IPK - all others are standardised against known constants.

In it, Feller points out the dependence of five of the SI base units on fundamental constants.
The current SI is founded on the seven base quantities, assumed to be independent, time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity, for which the SI base units are the second s, meter m, kilogram kg, ampere A, kelvin K, mole mol, and candela cd, respectively; see Table 1.
I also took into account the fact that not all of NIST's work can be neatly categorized by SI base units and the measurements associated with them.
