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 |
