Most of our UK, US and international buyers find it difficult when confronted with AWG sizing or mm. This tool helps in calculating the nominal equivalent ......
In the world of electrical engineering and electronics, understanding wire gauge sizes is crucial. Two common systems used are the American Wire Gauge (AWG) and the British Standard Wire Gauge (SWG), often referred to as simply 'gauge'. Converting between these systems can be a bit confusing, but it's essential for accurate and safe electrical work. Let's dive into the world of AWG to gauge conversion.
Before we delve into the conversion process, let's briefly understand both systems.
Converting AWG to gauge is necessary when working with international standards, or when dealing with older equipment that uses the gauge system. It's also useful for cross-referencing wire sizes in different regions or between different tools.

The conversion between AWG and gauge is not straightforward, as they are based on different number systems. However, a common formula used for conversion is:
Gauge = (36 - (36 - AWG) * 0.127) / 0.127
Let's break this down:
36 is a constant used in the conversion.(36 - AWG) calculates the difference between 36 and the AWG size.0.127 is a constant representing the diameter difference between each gauge size.Now, let's convert some AWG sizes to gauge using the formula above.
| AWG | Gauge |
|---|---|
| 12 | 16 |
| 14 | 18 |
| 16 | 20 |
| 18 | 22 |
Here are some common AWG to gauge conversions for quick reference:
If you're not a fan of math, there are plenty of online tools and calculators that can convert AWG to gauge for you. These tools can be found with a simple web search and can save you time and effort.
Converting AWG to gauge is a crucial skill for any electrical engineer or electronics enthusiast. Whether you're working with international standards or older equipment, understanding how to convert between these systems can save you time, effort, and potential mistakes. So, the next time you need to convert AWG to gauge, you'll know exactly how to do it.
