Hectometer
A hectometer (hm) is a unit of length in the metric system, equal to 100 meters. It is larger than a meter but smaller than a kilometer. While it is part of the official metric system, the hectometer is rarely used in daily life or science. For example, a running track is 400 meters long, which is 4 hectometers. The symbol for hectometer is "hm". Although not commonly seen, it can be useful for measuring medium-range distances, especially when kilometers feel too large and meters too small.
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.
