Meter (m)
Definition: The meter (m) is the base unit of length in the International System of Units (SI), defined by the speed of light in a vacuum. One meter is the distance light travels in 1/299,792,458 of a second.
History: The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. It has since been redefined multiple times, most recently in 1983 using the speed of light.
Current Use: The meter is universally used in science, engineering, and daily life for measuring objects, distances, and heights. It is the foundation of the metric system and adopted by nearly every country worldwide.
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.
