Micron

A micron, also known as a micrometer, is a unit of measurement in the metric system equal to one millionth of a meter (1 µm = 0.000001 m). It is commonly used to measure very small distances, such as the wavelengths of light, the size of microorganisms, and the dimensions of particles in various scientific fields, including biology, chemistry, and material science. The micron is significant in contexts such as microbiology, where it helps quantify the size of bacteria and other microorganisms, and in materials science, where it can be used to describe the thickness of films and coatings. The term "micron" can also refer to the micrometric scale, which highlights the importance of precision in measurements at these small scales.
