### Wire gauge size chart | AWG table

Wire cross sectional area calculations. 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): An (kcmil) = 1000× dn2 = 0.025 in 2 × 92 (36-n)/19.5 The n gauge wire's cross sercional area A n in square inches...
