Hi, early winding wire was often only single coated. Many of the wires available today are grade 2 (double coated) so actually overall diameter is greater for the same gauge number (which refers to the bare wire).

Micrometer is the only accurate way to size wire, resistance measurements can be hopelessly inaccurate (look up the tempco of copper!
