Chart for Enameled Copper Wire

From "Jon Tirone's Music and Electronic's Home Page."

Here is a chart that I drew up of some data for the use of copper wire. There are some things that I prefer using metric measurements as opposed to inches. This is one of them.

AWG #

Diameter in milli-meters

Surface area of diameter (Square mm)

Number of turns per cm

Kilos per kilometer

Resistance in ohms per kilometer

Capacity of current in amperes
