The base units are used to define all the unit atoms of The Unified Code for Units of Measure according to its grammar and semantics.
The selection of the base and the order of the units in the base are not normative. Any other base is acceptable as long as there is an isomorphism between the group of units generated by the other base system and this one. All base units are metric.
