Metric-to-AWG Conversion Chart
AWG is the American standard used to define the cross-sectional areas and diameters of solid, round electrical wire. The system is built around the wire drawing process — raw copper is pulled through a series of dies, each one reducing the wire to a smaller size, and the number of dies needed to reach the final diameter determines the AWG designation.
There is no straightforward way to convert AWG directly to metric measurements. The tables below show close approximations between AWG and metric sizes to help guide your selection.

Understanding Metric Cable Size and AWG Standards
Metric cable sizes are commonly used in Europe and many international markets, while AWG (American Wire Gauge) is the standard measurement system widely used in the United States and Canada. Converting metric cable sizes to AWG helps engineers, installers, and solar professionals select the correct conductor size for electrical safety, current capacity, and voltage drop performance in photovoltaic systems.
Why Metric-to-AWG Conversion Matters for Solar Cable Selection
Choosing the correct cable size is critical for solar power installations, especially in DC photovoltaic applications where efficiency and reliability are essential. A proper Metric-to-AWG conversion chart allows installers to accurately compare cable diameters, ampacity ratings, and conductor resistance. This helps ensure compliance with UL, IEC, and NEC standards while improving overall system performance and long-term durability.
Applications of Metric and AWG Cable Conversion in PV Systems
Metric-to-AWG conversion charts are widely used in solar panel wiring, battery storage systems, PV combiner boxes, inverters, and industrial electrical installations. Whether selecting UL PV wire, photovoltaic cable, or DC solar cable, understanding the relationship between metric cross-sectional area and AWG size simplifies cable sourcing, international project compatibility, and technical communication between global suppliers and contractors.
