Electric Wire - Calculating Cross-Section Areas
Cross-Section Area of Single Wire
The cross-section area of a round single wire can be calculated as
A = D2π / 4
= 0.7854 D2
where
A = cross-section area (mm2, in2)
D = diameter (mm, in)

Cross-Section Area of Bunched Wire
The cross-section area of bunched wires can be calculated as
A = n d2π / 4
= 0.7854 n d2
where
n = number of wires
d = single wire diameter (mm, in)

Diameter of a Single Wire Cross-Section Area
The diameter of a single wire cross-section area can be calculated as
D = (A 4 / π ) 1/2
= (1.2732 A ) 1/2
