Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.

The most common unit of measure for the copper thickness on a printed circuit board (PCB) is ounces (oz), as in mass. It is the resulting thickness when the mass of copper is pressed flat and spread evenly over a one-square-foot area. 1 oz will roughly equal 34.7 μm. [19]
Heavy copper is a layer exceeding three ounces of copper per ft 2, or approximately 4.2 mils (105 μm) (0.0042 inches) thick. Heavy copper layers are used for high current or to help dissipate heat. [citation needed] On the common FR-4 substrates, 1 oz copper per ft 2 (35 μm) is the most common thickness; 2 oz (70 μm) and 0.5 oz (17.5 μm ...

The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous metals and nonferrous metals such as aluminum or copper. Copper thickness, for example, is measured in ounces, representing the weight of copper contained in an area of one square foot.
Electrodeposited Copper Foil; Electrodeposited copper foil, also known as electrolytic copper foil, is produced by electroplating copper onto a rolling drum in a highly controlled manner. This type of copper foil has uniform thickness and excellent electrical conductivity, making it ideal for high-performance electronic applications.
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. Card stock thickness in the United States, where mils are also called points. [2] Gauge (diameter) of strings in stringed instruments [3] [4]
