In the world of electrical engineering and electronics, selecting the right wire gauge is crucial for ensuring the safety and efficiency of your circuits. Two common units used to measure wire gauge are millimeters (mm) and American Wire Gauge (AWG). If you're working with components from different regions or suppliers, you might need to convert between these two units. This guide provides a comprehensive mm to AWG conversion table and explains the process in detail.
Millimeters is a standard metric unit of length, widely used in many industries, including electronics. AWG, on the other hand, is an imperial unit specific to the wire industry. It was established in 1857 and is still widely used today, particularly in the United States.
AWG is not a linear scale; it's based on a complex mathematical formula that results in smaller diameter wires having larger gauge numbers. This might seem counterintuitive, but it's important to understand this relationship to accurately convert between the two units.

Converting millimeters to AWG is essential for several reasons. Firstly, many electronic components and datasheets specify wire gauge in AWG. Secondly, understanding the AWG equivalent of a wire's diameter in millimeters can help you select the appropriate wire for your application, ensuring it can handle the required current and fit into your connectors.
Here's a comprehensive mm to AWG conversion table for quick reference. Please note that this table provides approximate conversions, as the AWG system is not a direct linear scale.
| Millimeters (mm) | AWG |
|---|---|
| 0.127 | 40 |
| 0.152 | 38 |
| 0.178 | 36 |
| 0.211 | 34 |
| 0.254 | 32 |
| 0.305 | 30 |

| 0.406 | 26 |
| 0.457 | 24 |
| 0.508 | 22 |
| 0.559 | 20 |
| 0.635 | 18 |
| 0.711 | 16 |
| 0.787 | 14 |
| 0.864 | 12 |
| 0.953 | 10 |

If you need to convert a specific millimeter measurement to AWG, you can use the following formula:
d = 0.127 * (36 - 2 * AWG)
Where:
To find the AWG, rearrange the formula to solve for AWG:
AWG = 36 - (d / 0.127) / 2
Converting millimeters to AWG is a crucial skill for any electrical engineer or electronics hobbyist. Whether you're working with metric or imperial components, understanding the relationship between these two units can help you select the right wire for your application. Use the comprehensive conversion table provided in this guide for quick reference, or apply the formula to convert specific measurements. Always remember that the AWG system is not linear, and the conversions provided are approximations.
