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.
Gigameter (Gm)
Definition: A gigameter (Gm) is a unit of length equal to one billion meters (10^9 meters). It is used to describe large-scale distances, typically in astronomy and astrophysics.
History: The gigameter is part of the International System of Units and was introduced to handle extremely large measurements that are common in space science and the study of galaxies.
Current Use: Gigameters are used primarily in astronomy for measuring distances between large-scale celestial objects, such as stars, galaxies, and intergalactic spaces. It helps scientists express the vast scale of the universe.
