The formula to convert circular mils to AWG is:
\[ AWG = 39 - \left(\frac{\log_{10}(CM)}{\log_{10}(92)}\right) \times 19 \]
Where:
Let's say the circular mils (\( CM \)) is 10000. Using the formula:
\[ AWG = 39 - \left(\frac{\log_{10}(10000)}{\log_{10}(92)}\right) \times 19 \]
We get:
\[ AWG = 39 - \left(\frac{4}{1.963}\right) \times 19 \approx 39 - 38.72 \approx 0.3 \]
So, the American Wire Gauge (AWG) for 10000 circular mils is approximately 0.3.
Circular mils is a unit of area used especially for denoting the cross-sectional size of a wire or cable. One circular mil is the area of a circle with a diameter of one mil (one thousandth of an inch). This unit is commonly used in the United States for electrical wiring and is a convenient way to express the size of a wire without having to use the more complex square mils or square inches. The larger the number of circular mils, the larger the wire’s diameter and its ability to carry more current.
