Where L_{thou} is the length in thou and L_{centimeters} is its equivalent in centimeters.

The **thou** is a unit of measure for length equivalent to 1/1000 of an inch, that is 0.001 inches. It is also known as 'mil'. Introduced around 1844, it is still used today in manufacturing specifications of certain products such as printed circuit boards (ex. size of via holes and distance between lines), paper thickness (ex. newspaper paper thickness is around 2 to 4 thou), latex gloves.
