Instead this document describes conductors by their nominal size, determined by resistance rather than physical dimensions.

Mechanical properties measurement – Room temperature tensile test of reacted Nb3Sn composite superconductors. In engineering applications, it ice often most convenient to describe a wire in terms of its cross-section area, rather than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance. However this document allows an easy reference whereby the standard conductor sizes and reference to physical dimensions are maintained but given an exact meaning in terms of the electrical characteristics of a conductor.

The main problem being that not all copper has the same resistivity value, so, for example, a 4mm 2 conductor from two different suppliers may have different resistance values.
The cross-sectional area is also related to the maximum current that a wire can carry safely. Report error on page.
