Contexts of Use
The thou, or mil, is most commonly used in engineering and manufacturing. 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 (30 mils in US) in thickness.
- Manufacturing dimensions and tolerances, such as:
- In the manufacture of automobile engines (A typical example is the thickness of the head gasket, or the amount of material to be removed from the head to adjust the compression ratio of the cylinders.)
- In the servicing of automobile engines (Typical examples include a spark-plug gap or ignition points gap.)
- The manufacture of printed circuit boards (PCBs)
- Tolerance specifications on hydraulic cylinders
There are also compound units such as "mils per year" used to express corrosion rates.
A related measurement for area known as the circular mil, is based on a circle having a diameter of one mil.
