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.

Megameter
A megameter (Mm) is a unit of length in the metric system, equal to 1 million meters (1 Mm = 10⁶ meters or 1,000 kilometers). Megameters are used to measure very large distances, typically on a global or planetary scale. For example, the Earth’s diameter is about 12.7 megameters. Although it’s a valid metric unit, the megameter is rarely used in everyday life or science, as kilometers or other astronomical units are more common for such distances.
