WebNov 15, 2016 · How to find the cross sectional area of a wire. First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.”. Thus, 0.001 inch = 1 mil, 0.01 inch = 10 mils and so forth. Then we define the cross sectional area simply as the square of the wire’s diameter in mils ...
