Tabla de equivalencias AWG a milímetros

 TPI = turns-per-inch, vueltas por pulgada. Útil para el cálculo de bobinados. Diam(mm) = diámetro en milímetros. Circ-mils = área de la sección recta en mils circulares (1 circ-mil = d^2 siendo d el diámetro en mils). Ohms/kft = resistencia en Ohms por cada 1000 pies (1 pie = 0.3048 metros). Ft/Ohm = Número de pies requeridos para 1 ohm de resistencia. Amps = Tasa de corriente admisible basado en 750 circ-mils por ampere. MaxAmp = Corriente máxima admisible basado en 500 circ-mils por ampere.
