# AWG To mm2 Calculator

### Introduction

When working with electrical wiring, it's often necessary to convert between American Wire Gauge (AWG) and square millimeters (mm²). This conversion helps in understanding wire sizes in different measurement systems. Here, we'll provide a detailed guide on how to use an AWG to mm² calculator, the formula involved, and examples to help you make accurate conversions.

### How to Use

To use the AWG to mm² calculator, simply enter the AWG value into the input field and click the "Calculate" button. The result will display the corresponding mm² value.

### Formula

The formula to convert AWG to mm² is based on the diameter of the wire. The diameter (D) in inches for a given AWG can be calculated using the formula:

The cross-sectional area (A) in mm² is then calculated as:

### Example Solve

Let's convert AWG 10 to mm² using the formula:

- Calculate the diameter in inches:

- Convert the diameter to mm:

- Calculate the cross-sectional area:
