Gigameter
A gigameter (Gm) is a unit of length in the metric system, equal to 1 billion meters (1 Gm = 10⁹ meters). Gigameters are used to measure very large distances, often within the solar system. For example, the average distance from Earth to the Sun is about 150 gigameters, or 1 astronomical unit (AU). While not commonly used in everyday life, gigameters are helpful in astronomy and space science to describe distances between planets or other celestial bodies.
Famn
A famn (also spelled fathom in English) is a traditional Scandinavian unit of length used primarily for measuring the depth of water or length of ropes and cables. It is roughly equivalent to 6 Swedish feet, which translates to about 1.828 meters (approximately 6 feet).
The famn is similar in concept to the English fathom, based on the span of outstretched arms.
While largely obsolete today, the famn was commonly used in maritime contexts in Norway, Sweden, and Denmark and remains part of historical measurements.
