What is Micrometer?
The micrometer (symbol: µm), often called a micron, is an SI derived unit of length equal to $10^{-6}$ meters.
Common Uses
Micrometers are essential in biology for measuring the size of cells and bacteria, and in engineering (specifically microelectronics) to describe the size of components and manufacturing tolerances.
What is Mil?
A mil (also known as a thou) is a unit of length equal to 0.001 inches (1/1000th of an inch).
One mil is approximately equal to 0.0254 mm.
Common Uses
Mils are widely used in engineering and manufacturing to specify the thickness of materials (like plastic films, paper, and gold leaf) and the tolerances of machined parts. In electronics, it is the standard unit for designing Printed Circuit Boards (PCBs).
