This tiny imperial unit is indispensable in precision engineering, PCB (printed circuit board) design, and manufacturing, where conductor widths, dielectric coating thicknesses, and tight machining tolerances are specified in thou.

About Ares
An are (a) is a metric unit of area equal to 100 square meters (10 m × 10 m). Though less commonly used today, it served as an intermediate unit between square meters and hectares in the metric system. One are equals 0.01 hectares or about 119.6 yd². It is still occasionally used in some European countries for measuring medium-sized land plots, gardens, and vineyards. The dekameter-squared (dam²) is another name for the same unit.
