About these units
Russian Archin (archin)
The archin was a Russian unit of length equal to approximately 71.1 cm. Like many traditional European units, it was based on body proportions and was widely used in textile trade, tailoring, land measurement, and carpentry. Before Russia adopted the metric system in the early 20th century, the archin formed part of a larger system of customary units such as the sazhen and vershok. Merchants relied heavily on the archin when measuring cloth and other traded goods, making it central to the economic life of Imperial Russia. Today, the archin appears in historical documents, literature, and museum records. Understanding the archin is essential for historians studying Russian industrialization, daily commerce, and rural life before modernization efforts transformed the measurement landscape.
Roman Actus (actus)
The Roman actus was an ancient Roman unit of length measuring 120 Roman feet, or about 35.5 meters. It played an essential role in Roman land surveying and agriculture, forming part of the system used to organize farms, roads, and territorial divisions in the expanding Roman world. The actus helped define a square unit of land known as the actus quadratus, which was used for taxation, distribution of land to soldiers, and standardizing plots throughout Roman colonies. Surveyors relied on tools like the groma to lay out straight lines based on actus subdivisions, giving Roman lands their characteristic grid patterns. Although long obsolete, the actus provides key insights into Roman engineering, colonial administration, and agricultural policy. Many European land patterns can trace their roots back to Roman measurement practices — a testament to the enduring legacy of Roman surveying.
