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.
Ken
A ken is a traditional Japanese unit of length used mainly in architecture and construction. It measures the distance between two pillars in traditional Japanese buildings and is roughly equivalent to 6 Japanese feet (shaku) or about 1.82 meters (approximately 6 feet).
The ken was a standard module in Japanese design, influencing room sizes and proportions in temples, houses, and other structures. Its use helped maintain harmony and consistency in traditional building layouts.
Though largely replaced by the metric system today, the ken remains significant in studying traditional Japanese architecture and cultural heritage.
