About these units
Famn (famn)
The famn, related to the English fathom, was a Scandinavian unit roughly equal to 1.78 meters. Like other fathoms, it originated as the distance between a person's outstretched arms, making it a natural measure for tasks performed at arm's length. Historically, the famn was used in maritime contexts, forestry, and measuring firewood. Sailors relied on it when describing water depth, rope lengths, and the dimensions of boats. On land, stacked firewood was often quantified in famnar, making the unit central to resource management in cold northern regions. Today, the famn has largely disappeared from practical use, but it continues to appear in maritime literature, folklore, and historical accounts. Its surviving references help illuminate the working methods and daily experiences of Nordic sailors, fishermen, and rural communities prior to metrication.
Sun's Radius (R☉)
The Sun's radius is approximately 696,340 km, representing the distance from the Sun's center to its photosphere. This measure is essential for understanding solar structure, luminosity, and energy output. Stellar astronomers use the Sun's radius as a benchmark for comparing other stars, often expressing their size in multiples of R☉. Precise knowledge of the Sun's radius aids in modeling solar evolution, predicting solar cycles, and calculating irradiance impacting Earth's climate and space weather. It serves as a fundamental scale for both astrophysics and heliophysics.
