About these units
Rod (US Survey) (rd (US))
The US Survey Rod equals 16.5 US Survey Feet (~5.0292 meters). Like the chain and furlong, it serves as a subdivision of larger units, maintaining consistency with historic Gunter-based measurements. Surveyors historically used rods to measure short distances, delineate boundaries, and calculate acreages. Its simple relationship to chains and furlongs made it practical for field measurements without complex arithmetic. Today, the US survey rod primarily appears in historical records, legal surveys, and when referencing pre-metric property data, providing continuity between older and modern surveying conventions.
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.
