How to find the cross sectional area of a wire. First, we define that the diameter of our wire is taken in thouhs of an inch where one onethouh of an inch is called "one mil.". Thus, inch = 1 mil, inch = 10 mils and so forth. Then we define the cross sectional area simply as the square of the wire's diameter in mils ...

The AWG standard includes copper, aluminum and other wire materials. Typical copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire. The table below can be used to convert American Wire Gauge (AWG) to square mm cross sectional area.

1 Introduction There are several applications in which helical grooves are required on a cylindrical surface. Examples include lubrication grooves for journal bearings, cooling grooves for molds, raceways for ball nuts, and internal and external threads. There are alternative processes to produce such grooves. One of them is helical milling.
