Calculate Diameter ↔ cross section ↔ AWG: 1mm, mm2, AWG
Converting wire sizes between diameter (d), cross section area (A) and AWG (American wire gauge). Note that higher AWG number means a thinner wire. Diameter to area and back: A=π•d2/4 d=2•√A/π
Diameter in mm to AWG and back: AWG=-39•log92(d/0.127mm)+36 d=0.127mm•92(36-AWG)/39
