League
A league is an old unit of distance that was commonly used in the past, especially for measuring distances on land or sea. Traditionally, one league equals about 3 miles or roughly 4.8 kilometers. The exact length of a league could vary by country and time period. It was often used by sailors and travelers to describe how far they had gone. Although the league is mostly obsolete today, it still appears in literature and historical contexts.
Russian Archin
The archin (also spelled arshin) is a traditional Russian unit of length that was widely used before the adoption of the metric system. It is approximately equal to 28 inches or 0.7112 meters.
The archin was commonly used in measuring cloth, land, and building dimensions in Russia and neighboring regions. It roughly corresponds to the length of a forearm from the elbow to the tip of the middle finger, similar to the cubit.
Though obsolete today, the archin remains an important part of Russian historical measurements and appears in older legal and trade documents.
