20 mm² to AWG: A Comprehensive Guide to Converting Wire Sizes
When it comes to electrical wiring, understanding the different wire sizes and their corresponding measurements is crucial. Two of the most common wire size measurement systems are the metric system, which uses square millimeters (mm²), and the American Wire Gauge (AWG) system. In this article, we will explore the conversion of 20 mm² to AWG and provide a comprehensive guide to help you navigate these different measurement systems.
What is AWG?
The American Wire Gauge (AWG) system is a standardized method of measuring wire sizes. It uses a logarithmic scale to measure the diameter of a wire, with smaller numbers indicating larger wire diameters. The AWG system is commonly used in North America and is widely accepted as the standard for electrical wiring.
What is mm²?
The metric system uses square millimeters (mm²) to measure wire sizes. This system is more straightforward, as it measures the cross-sectional area of the wire in square millimeters. The mm² system is commonly used in Europe and other parts of the world.
20 mm² to AWG Conversion
So, what is the equivalent AWG size for a 20 mm² wire? The conversion is as follows:
- 20 mm² ≈ 7 AWG
This means that a wire with a cross-sectional area of 20 square millimeters is equivalent to a 7 AWG wire.
