convert 4 awg to mm2 - IOT Wiring Diagram

Converting between American Wire Gauge (AWG) and mm2 can be a tricky process, but with the right tools and knowledge it’s easy to understand. AWG is the US standard of measurement for electrical wire, while mm2 is the international metric unit for electrical wiring size. Knowing the conversion between AWG and mm2 can help when planning for your electrical needs and can save you time and money by not having to Google the measurements every time.

For starters, 4 AWG translates to 21.15 mm2, which is the equivalent of an 8-gauge wire. All it takes is a simple calculation to reveal the answer. You’ll simply need to take the diameter of the wire, measured in mils, and multiply it by 0.0126 and then by itself, then again by 0.7854 for the final number. This will give you the area in square millimeters. It’s important to use the correct diameter of your wire for accuracy.

Although accurate conversions are available online, knowing how to convert 4 AWG to mm2 by yourself is beneficial for any electrician. Calculations done manually allow you to double check all numbers if needed and add them up faster than searching on the internet. Furthermore, having a basic understanding of the AWG-mm2 conversion system makes navigating electrical needs much simpler.
