A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It is equal to π /4 square mils or approximately 5.067 × 10 −4 mm 2 .
The thou, or mil, is most commonly used in engineering and manufacturing in non-metric countries. For example, in specifying: The thickness of items such as paper, film, foil, wires, paint coatings, latex gloves, plastic sheeting, and fibers For example, most plastic ID cards are about 30 thou (0.76 mm) in thickness.

The first metric Melbourne Cup was raced in November 1972. An early change was the metrication of horse racing. This was facilitated because the furlong (one-eighth of a mile) is close to 200 m. Therefore, the Melbourne Cup was changed from 2 mi to 3,200 m, a reduction of 19 m or about 0.6%. The first metric Melbourne Cup was raced in November ...
