About these units
Kilometer (km)
A kilometer is equal to one thousand meters and serves as the standard large-scale terrestrial distance unit in nearly all countries that use the metric system. It provides a convenient middle ground between the human walking scale and the geographic scale of cities, regions, and countries. Road signs, maps, geographic information systems, and national transportation networks rely heavily on kilometers to express distances succinctly and uniformly. Because kilometers integrate seamlessly into the metric system, they also appear in scientific contexts—ranging from geologic fault lengths to atmospheric layer thicknesses. In natural disasters such as earthquakes or volcanic eruptions, distances from epicenters or vents are often measured in kilometers to communicate scale effectively to the public. The kilometer's widespread use demonstrates the power of the metric system's decimal structure, offering simplicity and international standardization.
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 Today, the archin appears in historical documents, literature, and museum records.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.
