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.
Summary:
1 ken ≈ 1.82 meters (6 feet)

Statute League
A statute league is a traditional unit of distance used primarily on land and defined as 3 statute miles, which equals about 4.83 kilometers or 15,840 feet. It was commonly used in English-speaking countries for measuring distances before the metric system became widespread. The statute league is different from the nautical league, which is based on nautical miles and used at sea. Although largely obsolete today, the statute league is still found in historical texts and older maps.
