AWG calculation for strands

The AWG figure basically stands for a cross-section only. Therefore, any dimension relative to both single wires as well as strands is expressed as such an AWG figure.

Just to make matters more complicated, it is the construction of a strand that has a crucial impact on some of its major properties like flexibility, resistance, conductivity or tensile strength. This aspect has led to the inclusion of the construction whenever an AWG indication is applied. An AWG28 strand, for instance, may consist of seven AWG36 single wires. This is reflected by the designation "AWG28 7/36".

Practitioners have developed approximations for the quick calculation of strand sizes, which can be employed to a certain extent.
