This page allows you to convert length values expressed in thou to their equivalent in microns.
Enter the value in thou in the top field (the one marked "thou"), then press the "Convert" button or the "Enter" key. The converter also works the other way round: if you enter the value in microns in the "µ" field, the equivalent value in thou is calculated and displayed in the top field.
Where Lthou is the length in thou and Lmicrons is its equivalent in microns.
Reverse formula (microns to thou)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.

The micron (µ), is a unit of length that is equivalent to 10-6 m (one millionth of a meter). It is infact an alternate name for micrometer. The unofficial term micron is still used in many fields of technology, such as electronic component manufacturing and specification.
