A ken is a traditional Japanese unit of length equal to six shaku and is standardized as approximately 1.818 meters. It is used in architecture to denote bay widths between structural pillars.

What does the Planck length represent?

The Planck length is the natural length scale defined by fundamental constants, indicating the scale where quantum-gravitational effects become significant and classical space concepts may no longer apply.

Why convert ken to Planck length?

Converting ken to Planck length helps bridge traditional architectural measurements with fundamental physics scales, useful in theoretical physics research and educational contexts.
