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.

Nautical League
A nautical league is a unit of distance once used at sea, mainly by sailors and navigators. It equals 3 nautical miles, which is about 5.56 kilometers or 3.45 miles. Nautical leagues were used to measure longer distances during voyages before modern navigation tools became common. While the nautical mile is still widely used today in maritime and aviation navigation, the nautical league is mostly obsolete and rarely used.
