**Converting 1.5 mm² to AWG: A Simplified Guide**

When working with electrical wires, it's essential to understand the different measurement units used to describe their size. Two common measurement systems are the Square Millimeter (mm²) system, widely used in Europe, and the American Wire Gauge (AWG) system, commonly used in North America. In this article, we'll explore how to convert 1.5 mm² to AWG and provide a brief overview of both measurement systems.

**What is mm²?**

The Square Millimeter (mm²) system is a unit of measurement that represents the cross-sectional area of a wire. It's calculated by multiplying the diameter of the wire by itself. For example, a wire with a diameter of 1.5 mm would have a cross-sectional area of 1.5 mm².

**What is AWG?**

The American Wire Gauge (AWG) system is a standard used in North America to measure wire sizes. AWG measures the diameter of the wire, with smaller gauge numbers indicating larger wires and vice versa. The AWG system is based on a geometric progression, where each gauge number represents a decrease in wire diameter of approximately 1.122.

**Converting 1.5 mm² to AWG**

To convert 1.5 mm² to AWG, we need to find the equivalent wire diameter in inches. Using a wire size chart or calculator, we can determine that a wire with a cross-sectional area of 1.5 mm² has a diameter of approximately 0.071 inches.

Now, let's refer to an AWG chart:

AWG | Diameter (inches) |
---|---|

15 | 0.072 |

16 | 0.064 |

17 | 0.056 |

As we can see, a wire with a diameter of 0.071 inches falls between AWG 15 and AWG 16. To be more precise, we can interpolate the value:

**1.5 mm² ≈ AWG 15.5**

Therefore, a wire with a cross-sectional area of 1.5 mm² is approximately equivalent to an AWG 15.5 wire.

**Conclusion**

In this article, we've demonstrated how to convert 1.5 mm² to AWG. Remember that the AWG system is based on wire diameter, while the mm² system is based on cross-sectional area. By understanding both systems and their conversion, you'll be better equipped to work with electrical wires and ensure accurate measurements in your projects.
