Solution Steps

23 AWG to mm:

Formula: d(mm) = 0.127 × 92^((36 − AWG) / 39)
= 0.127 × 92^((36 − 23) / 39)
= 0.574 mm

Cross-sectional area:
A = π × (d/2)²
= π × (0.574/2)²
= 0.259 mm²

Frequently Asked Questions

What is 23 AWG in mm?

23 AWG wire has a diameter of 0.574 mm and a cross-sectional area of 0.259 mm².

What is 23 AWG wire used for?

23 AWG is used in Cat6 and Cat6a Ethernet cables. The slightly thicker conductor reduces resistance and supports better high-frequency performance compared to 24 AWG.

23 awg to mm (0.573 mm) is used in telephone wiring and some structured cabling. Understanding 23 awg to mm helps when selecting the correct wire for data and communication installations. For reference, see the American Wire Gauge — Wikipedia.
