one mil is the circular mil area of 12 awg.
what is the circular mil area of 12 awg?
one mil
section::::awg circular mil formula.









































the formula to calculate the circular mil for any given awg (american wire gauge) size is as follows. a represents the circular mil area for the awg size n.









































bullet::::- for example, a number 12 gauge wire would use n = 12; and the calculated result would be 6530 circular mils









































sizes with multiple zeros are successively larger than the number 0 gauge size and can be denoted using "number of zeros/0"; for example 4/0 for the number 0000 gauge. for an m/0 awg wire size, use
circular mil
1000 circular mil equals , so for most purposes, a ratio of 2 mcm ≈ 1 mm can be used with negligible (1.3%) error.









































section::::equivalence to other units of area.









































as a unit of area, the circular mil can be converted to other units such as square inches. a 0000 awg solid wire is defined to have a diameter of exactly 0.46 inch.









































formula 1: circular mil









































formula 2: square mil









































formula 3: square inch









































1 circular mil is approximately equal to:









































bullet::::- 0.7854 square mils (1 square mil is about 1.273 circular mils)
