Tabla de conversión de medidas métricas a AWG
AWG es el estándar estadounidense utilizado para definir el área de sección transversal y el diámetro de los conductores eléctricos sólidos y redondos.
Este sistema se basa en el proceso de trefilado del alambre: el cobre se hace pasar a través de una serie de matrices que reducen gradualmente su diámetro. El número de etapas necesarias para alcanzar el tamaño final determina la designación AWG del conductor.
No existe una forma sencilla de convertir directamente las medidas AWG a medidas métricas. Las tablas que aparecen a continuación muestran aproximaciones cercanas entre las medidas AWG y las métricas para ayudarle a elegir la opción adecuada.

Understanding Metric Cable Sizes and the AWG Standard
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.
The conversion between metric sizes and AWG helps engineers, installers, and solar professionals select the correct conductor size, ensuring electrical safety, current-carrying capacity, and proper voltage drop performance in photovoltaic systems.
Why Metric–AWG Conversion Is Important for Solar Cable Selection
Selecting the correct cable size is critical in solar installations, especially in photovoltaic (DC) applications where efficiency and reliability are essential. A metric-to-AWG conversion chart allows installers to accurately compare cable sizes, current-carrying capacity (ampacity), and conductor resistance.
This helps ensure compliance with standards such as UL, IEC, and NEC, while improving overall system performance and long-term durability.
Applications of Metric and AWG Conversion in Photovoltaic (PV) Systems
Metric-to-AWG cable conversion is widely used in solar panel wiring, battery energy storage systems, photovoltaic combiner boxes, inverters, and industrial electrical installations.
Whether selecting UL PV cables, photovoltaic cables, or DC solar cables, understanding the relationship between metric cross-sectional area and AWG sizes simplifies:
-
Cable selection and procurement
-
International project compatibility
-
Technical communication between global suppliers and contractors
Overall, this conversion helps streamline electrical design, improve engineering accuracy, and ensure more efficient implementation of solar energy systems.
