__________________________________________________ 在硬件设计和线缆选型过程中，我们经常会碰到诸如16AWG、18AWG、24AWG、26AWG等等表示电缆直径的方法。实际上AWG(American Wire Gauge)是美制电线标准的简称，AWG值是导线厚度（以英寸计）的函数。一般以下表表示AWG与公制、英制单位的对照。其中，4/0表示0000，3/0表示000，2/0表示00，1/0表示0。例如，常用的电话线直径为26AWG，约为0.4mm。

AWGMCM线规对照表 2
在硬件设计和线缆选型过程中，我们经常会碰到诸如16AWG、18AWG、24AWG、26AWG等等表示电缆直径的方法。实际上AWG(American Wire Gauge)是美制电线标准的简称，AWG值是导线厚度（以英寸计）的函数。一般以下表表示AWG与公制、英制单位的对照。其中，4/0表示0000，3/0表示000，2/0表示00，1/0表示0。例如，常用的电话线直径为26AWG，约为0.4mm。
