Wire Gauge Cross Sectional Area
American wire gauge awg versus square mm cross sectional area engineering toolbox resources tools and basic information for engineering and design of technical applications.
Wire gauge cross sectional area. A n mm 2 π 4 d n 2 0 012668 mm 2 92 36 n 19 5. The awg standard includes copper aluminum and other wire materials. Area mm 2 π 4 diameter 2.
Thus 0 001 inch 1 mil 0 01 inch 10 mils and so forth. Increasing gauge numbers denote decreasing wire diameters which is similar to many other non metric gauging systems such as british standard wire gauge swg but unlike iec 60228 the metric wire size standard used in most parts of the world. The circular mil cm is a unit of area used especially to denote cross sectional size of a wire or cable.

Wire gauge is a measurement of a wire either its diameter or cross sectional area. Then we define the cross sectional area simply as the square of the wire s diameterin mils and call that our area in units of circular mils.
Search is the most efficient way to navigate the engineering toolbox. Steps to find the cross sectional area. The n gauge wire s cross sercional area a n in kilo circular mils kcmil is equal to 1000 times the square wire diameter d in inches in.
When dealing with wire gauge the characteristics of a wire usually specified on a chart is the wire s size specified in awg diameter area feet per pound ohms per 1000ft and current capacity in amps. The cross section refers to the area of each wire of a cable and its size depends on several factors. Telephone wire is usually 22 24 or 26.
The formula to find the cross sectional area of the wire in square millimeters is. The higher the gauge number the smaller the diameter and the thinner the wire. Wire stranding charts solid and stranded conductor awg chart awg size total strands strand size type construction nominal diameter inches mm mils mm2 approimate weight lbs 1000 kg km nom.
