AWG (American Wire Gauge) es un estándar para distinguir los diámetros de los cables, también conocido como calibre Brown & Sharpe.
Este sistema estandarizado de calibre de cables empezó a utilizarse en Estados Unidos en 1857. El número que precede a AWG (como 24 AWG, 26 AWG) representa el número de orificios que debe atravesar un cable antes de alcanzar su diámetro final.
Cuanto mayor sea el número, más agujeros atravesará el cable y menor será su diámetro. SWG (Standard Wire Gauge) es uno de los estándares de la industria del alambre y el cable. BWG (Birmingham Wire Gauge) se refiere al calibre de alambre de Birmingham, que indica el grosor o diámetro del material.

La resistividad es una magnitud física utilizada para representar las características de resistencia eléctrica de diversos materiales. La resistencia de un hilo de un determinado material, de 1 metro de longitud, con un área de sección transversal de 1 milímetro cuadrado, y a temperatura ambiente (20℃), se denomina resistividad de este material.
Según la Ley de Ohm R=PL/S, se puede calcular la resistencia del conductor. R es la resistencia, en ohmios. P es la resistividad, en ohmios-metro, y está relacionada con el material del conductor. L es la longitud del conductor, en metros. S es el área de la sección transversal del conductor, en metros cuadrados.
