The ken is a traditional Japanese unit of length used mainly in architecture, equal to about 1.818 meters and representing bay widths between pillars.

Why convert ken to kilometers?

Converting ken to kilometers helps interpret traditional measurements in modern metric terms, useful in mapping, engineering, and restoration work.

Is the conversion exact?

No, the ken can vary depending on historical context, so the conversion to kilometers is approximate.
