About these units
Gigameter (Gm)
A gigameter, one billion meters (10⁹ m), moves firmly into interplanetary territory. Astronomers use gigameters to express distances within the solar system, such as the average separation between planets or the orbital paths of spacecraft. For example, the Earth–Moon distance (~384,000 km) can be expressed as 0.384 Gm, and distances to nearby planets often fall in the range of tens or hundreds of gigameters depending on orbital positions. The gigameter is particularly useful in scientific models where distances are massive but still fall short of interstellar scales. It reduces the need for unwieldy scientific notation and gives researchers a manageable unit for calculations involving gravitational fields, orbital dynamics, and space mission planning.
Aln (aln)
The aln was a traditional Swedish unit of length equal to roughly 59.4 cm, though its exact value varied slightly by region and period. It belongs to the broader family of "ell" measurements used across Europe, originally based on the length of a human forearm. The aln played a crucial role in Swedish commerce, especially in the textile industry, where cloth was measured by stretching it along standardized rods or boards marked in aln lengths. Because such goods were often woven locally and traded regionally, the aln helped regulate and unify commercial practices before the adoption of the metric system. Although obsolete today, the aln survives in historical texts, architectural references, and Scandinavian museum records. Understanding the aln helps scholars interpret pre-modern construction records, land measurements, and traditional clothing industries, revealing a great deal about everyday life in early Sweden.
