Converting 0.2mm² to AWG: A Comprehensive Guide

This article explains how to convert a wire's cross-sectional area in square millimeters (mm²) to the American Wire Gauge (AWG) system.

Understanding Wire Gauge

The American Wire Gauge (AWG) is a standardized system used to describe the diameter of round wires, primarily in the United States and Canada. Higher AWG numbers correspond to smaller wire diameters. This means a 22 AWG wire is thinner than a 10 AWG wire.

Conversion Process

The conversion between mm² and AWG is not a simple linear relationship. It involves using a specific formula and a table of AWG sizes. Here's how to approach the conversion:

  1. Find the Area in Circular Mils (CM):

    • One circular mil (CM) is the area of a circle with a diameter of one mil (0.001 inch).
    • To convert mm² to CM, use the following formula: CM = (mm² * 1973.5)
    • In our case, 0.2 mm² converts to: 0.2 mm² * 1973.5 = 394.7 CM
  2. Use the AWG Table:

    • Consult a table that lists AWG sizes and their corresponding circular mil (CM) values. You can find such tables online or in electrical handbooks.
    • Locate the CM value closest to your calculated 394.7 CM.
    • This value will fall between two AWG sizes. For example, if your calculated value falls between 331 CM (AWG 20) and 417 CM (AWG 19), then the closest AWG size is AWG 19.

Conclusion

By following these steps, you can easily convert a wire's cross-sectional area in square millimeters to its equivalent AWG size. Remember that the AWG system provides a standard way to categorize wire diameters, ensuring consistent communication and selection in electrical applications.
