中归纳出的AWG与英寸的关系如下：AWG=Alginch-B其中，A＝-19.93156857，B＝9.73724。通常用AWG(AmericanWireGauge,美国线规)或者密耳圆(CircularMil,直径1mil即0.001inch=0.0254mm的导体的截面积)1cmil=(1mil)^2 例如:36AWG=5mils是指直径为5密耳，而不是指5个密耳圆的面积4/0AWG=460mils问：怎样由AWG换算出mils？答：每AWG之间直径呈等比数列递增，等比“X”算法：x=(460/5)的1/39次方=1.122932mils 其中39为4/0AWG与36AWG之间的AWG数即直径从5密耳按等比增加到460密耳的等比系数,因此线径(密耳)=5*｛x的(36-AWG)次方｝ 例34AWG=5*1.122932^(36-34)=6.3mils=0.16mm 18AWG=5*1.122932^(36-18)==40.3mils=1.023mm(导体直径）
