B&S = AWG. No conversion needed.
Due to the widespread adoption of the Brown & Sharpe standard across the United States, it was eventually formalized as the . While the name changed to reflect national usage, the underlying mathematical formulas and dimensional tables remained identical to the original Brown & Sharpe specifications. awg to b&s
In modern electrical, industrial, and automotive contexts, . When you see a wire labeled “4 B&S” or “4 AWG,” they refer to the exact same physical size, current capacity, and resistance. B&S = AWG

While "AWG" is the standard term in the United States, "B&S" remains common in Australia and some Commonwealth countries, particularly for heavy-duty automotive and marine cabling. AWG to B&S Conversion Chart
