Circular Mils Explained Blue Sea Systems

网页One Circular Mil is a unit of area equal to that of a circle .001" in diameter (.0005" radius). The actual area of a Circular Mil is: When wires get very large their sizes are sometimes shown as "MCM", such as 250MCM. MCM means Thousand (M) Circular (C) Mils (M). A 250MCM wire is wire with an area equal to 250 x 1000 Circular Mils.
