What is a ken in traditional measurement?

A ken is a traditional Japanese unit of length equal to six shaku, approximately standardized as 1.818 meters, commonly used for space between pillars in architecture.

Why convert ken to millimeters?

Converting ken to millimeters helps translate traditional Japanese architectural dimensions into precise modern metric units for engineering, manufacturing, and digital modeling.

Can the conversion from ken to millimeters vary?

Yes, the ken length can vary historically and regionally, so the standardized conversion used here might not apply universally.
