Micron (µ)
Definition: A micron (µ) is a unit of length equal to one-millionth of a meter (10^-6 meters). It is also known as a micrometer and is used for measuring small objects like bacteria, cells, and micro-particles.
History: The micron was introduced in the late 19th century during the advancement of microscopy. It provided scientists with a standardized unit to describe very small dimensions, especially in biological and material sciences.
Current Use: Microns are widely used in fields such as microbiology, materials science, and nanotechnology. They help measure the size of cells, dust particles, fibers, and in the manufacturing of high-precision components.
Exameter (Em)
Definition: An exameter (Em) is a unit of length equal to 10^18 meters. It is used primarily in theoretical physics and astronomy for describing vast cosmic distances.
History: As the metric system expanded, large-scale units like the exameter were introduced to accommodate astronomical and scientific measurements requiring extremely large distances.
Current Use: Exameters are rarely used in everyday applications but appear in astrophysics when discussing interstellar distances, black hole measurements, and the size of cosmic structures.
