线缆的AWG与mm对照表

表一：AWG与mm对照表近似类比：(依次为1/3的关系)1 AWG=7.5mm10 AWG=2.5mm20 AWG=0.8mm30 AWG=0.20mm只用记住10号线规为2.5mmAWM=Appliance Wiring MaterialAWG=American Wring Gauge.NO.28一般也寫成28AWG,芯線的構成常用二種方式:1. 0.322/12. 0.127/7.也寫成36AWG/7.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。

换算后的常用AWG和线径值，如下：#AWG号数 mm直径厘米圆平方厘米(c/m)8 3.264 16 4409 2.906 1 296010 2.588 1038011 2.305 823412 2.053 653014 1.628 411015 1.450 325716 1.291 258017 1.150 204818 1.024 162019 0.9116 128821 0.7229 81022 0.6438 64523 0.5733 509.424 0.5106 40533 0.1798 50.13 群导体计算的方法或公式：加上单一导体的线径值总和，并比较上表求得。

如果值落入两者之间，取比较少的值。

40股群导体线的线径值为，如每一芯为24 Guage = 40 x 405 c/m = 16，200 c/m = 9 AWG(得出值落入12960c/m和16440c/m之间)快速求得线径值的方法：两条(AWG)相加时，该单一线径值减3. ex. 2 x 18 AWG = (18-3=) 15 AWG三条(AWG)相加时，该单一线径值减5. ex. 3 x 24 AWG = (24-5=) 19 AWG四条(AWG)相加时，该单一线径值减6. ex. 4 x 10 AWG = (10-6=) 04 AWG请记得“快速求得线径值的方法” 一些案例也许边际会不正确，只采用此方式为大原则有很多用户对美国Omega热电偶线的线规不是很清楚，下面提供线规对照表，AWG线规与公制、英制单位对照AWG（American Wire Gauge），也被称作布朗/夏普线规（Brown/Sharpe wire gauge），在美国，从1857年开始就被作为一种标准的线规使用，它广泛应用于圆柱体，立方体，有色金属及电力控制线的直径测量，它的截面积决定了导体的载流能力。
