Convert American Wire Gauge (AWG) to diameter and area values in inches (in) millimeters (mm) or circular mil area (CMA) using the Wire Size Conversion ......
In the world of wire gauges, the American Wire Gauge (AWG) system is widely used to measure the diameter of electrical wires. However, sometimes you might need to convert AWG to inches to ensure precise measurements for your projects. This guide will walk you through the process, using an AWG to inches calculator, and provide you with a better understanding of the conversion.
Before diving into the conversion, let's briefly understand the AWG system. It's a standard used primarily in the United States for measuring the diameter of round, non-ferrous, electrically conductive wires. The gauge number increases as the wire's diameter decreases, which might seem counterintuitive. This is because the AWG system was originally designed for nails and the smaller the nail, the larger the gauge number.
Converting AWG to inches is beneficial in several scenarios. For instance, you might need to ensure that a wire fits perfectly into a specific space, or you could be designing a custom wire harness where precise measurements are crucial. Whatever the reason, using an AWG to inches calculator can help you achieve accurate results.

Using an AWG to inches calculator is straightforward. You simply input the AWG number you want to convert, and the calculator will provide you with the equivalent measurement in inches. Here's a simple step-by-step guide:
If you prefer to calculate the conversion manually, you can use the following formula:
Diameter in inches = (36 - 2 * AWG) / 36

For example, if you're working with a 16 AWG wire, the calculation would be:
Diameter in inches = (36 - 2 * 16) / 36 = 0.050 inches
Here are some common AWG to inches conversions to give you an idea of the scale:
| AWG | Diameter in inches |
|---|---|
| 12 | 0.102 inches |
| 14 | 0.083 inches |
| 16 | 0.050 inches |
| 18 | 0.036 inches |
| 20 | 0.026 inches |
When working with wire gauges, here are a few tips to ensure precise measurements:
In conclusion, converting AWG to inches is a straightforward process that can be done using an AWG to inches calculator or manually with the provided formula. Precise measurements are crucial in many projects, so understanding this conversion can help you achieve the best results.
