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.
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.
