# AWG Size Chart

The table below shows the AWG wire size and the equivalent diameter in both inches (in) and mm as well as cross-sectional area in cmils, kcmils and sq.mm.

To find equivalent wire sizes for various AWG sizes

Using the table, for example, 0000 (4/0) AWG has an equivalent diameter of 0.46 inches or 11.684 mm. In terms of cross-sectional area,

0000 (4/0) is equivalent to 211,600 cmils, 212 kcmil or 107 mm2 (sq.mm)

How to use the table

The higher the AWG number, the smaller the wire size (diameter). For example, 1 AWG size is larger than 2 AWG. As you move down the AWG column in the table above, the wire becomes thinner.

# 1. What is bigger 2 AWG or 4 AWG?

2 AWG is bigger than 4 AWG.

# 2. What size wire is bigger 1 0 or 2 0?

2/0 AWG is bigger than 1/0 AWG. Similarly:

• 0000 (4/0) is thicker than 000 (3/0)
• 000 (3/0) is thicker than 00 (2/0)
• 00 (2/0) is thicker than 0 (1/0).

Note:

AWG wire size 1 with a diameter of 0.2893 in has an area equivalent to 83,694 cmils. This refers to solid copper wire
