Electric Wire - Calculating Cross-Section Areas

Sponsored Links

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
