Sometimes.

Circular mills is a way of measuring wire size. It's a measurement of area. It's used to state the cross sectional area of round wire, because the current (electricity) carrying ability of wire is related to this area.

In the U.S. wire gauge (18 gauge, 14 gauge, etc.) is used to state wire sizes until they become large. Large sizes (larger than 0000 gauge maybe) are stated in circular mills, but the size of any wire could be stated in circular mills.
