A micron, also known as a micrometer, is a unit of measurement commonly used in science, engineering, and technology to specify distances and sizes. It is equal to one millionth of a meter, or 0.0001 centimeters.
In practical applications, a micron can be used to measure the size of particles, such as those found in air or water. It is also commonly used to measure the thickness of materials, such as thin films, coatings, and fibers.
