Mils & Microns History and Facts:

A mil (or thou) is an imperial unit equal to 0.001 inch. It’s widely used in North America to specify the thickness of materials such as plastic films, wires, or printed circuit board layers.

A micron, or micrometer [µm], is a metric unit equal to one-millionth of a meter (0.000001 m). It is commonly used in science, engineering, and manufacturing for measuring very small distances or film thicknesses.

Converting mils to microns helps manufacturers and engineers align specifications across imperial and metric standards. For example, 2 mils equals 50.8 microns.
