What is the ken unit used for?

Ken is a traditional Japanese length unit commonly used in architecture to define bay widths between structural pillars and in room and tatami sizing.

How is the US survey fathom defined?

The US survey fathom is a unit of length equal to 6 US survey feet, used primarily for nautical measurements like water depths and line lengths.

Why might conversions between ken and fathom introduce slight discrepancies?

Because the ken varies slightly in length historically and is approximated as 1.818 meters, while the fathom (US survey) has a precise definition, minor differences can occur.
