This page allows you to convert length values **expressed in microns** to **their equivalent in mils**.

Enter the value in microns in the top field (the one marked "µ"), then press the "Convert" button or the "Enter" key. The converter also works the other way round: if you enter the value in mils in the "mil" field, the equivalent value in microns is calculated and displayed in the top field.

Where L_{microns} is the length in microns and L_{mils} is its equivalent in mils.

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.

The **mil** is a unit of measure typically used in manufacturing and engineering for describing distance tolerances with high precision or for specifying the thickness of materials. One mil is equal to one thousandth of an inch, or 10^{-3} inches.

The mil is also referred to as thou.

The closest unit to the mil in the metric system is the micrometer: One mil is equal to 25.4 µm.
