This table shows the correspondence between AWG (American Wire Gauge), a standard used primarily in the United States, and SQ (square millimeters), which is commonly used in countries like Japan. In the AWG system, a smaller number indicates a thicker wire, while SQ represents the cross-sectional area of the conductor in mm². This table is useful for comparing and converting wire sizes between different standards.
