電阻不管 0603, 0805 , 1206其實大多用英制去算, 若用公制那就好算多了.....
1000mil = 25.4mm , 所以 1mm = 39.37mil
0603為長 60mil, 寬 30mil 所以長 60mil / 39.37 = 1.52mm 寬30mil / 39.37 = 0.76mm
0805為長 80mil, 寬 50mil 所以長 80mil / 39.37 = 2.03mm 寬50mil / 39.37 = 1.27mm
1206為長 120mil 寬 60mil 所以長 120mil/ 39.37 = 3.04mm 寬60mil /39.37 = 1.52mm
以此類推.......................................

0603 0805 1206已经是英寸了
所以换算为mm应当分别是 1608 2012 3216
直接乘2.54
