About kilometre and ken
Kilometre: A kilometre is 1,000 metres — the metric unit for road and map distances.
Ken: A ken is a Japanese unit of 6 shaku, standardised since 1891 as 60/33 m ≈ 1.818 m.
The metric units (km, m, cm, mm, µm) are exact by definition, and the imperial units (mile, yard, foot, inch, nautical mile) use their exact international values. Traditional units (hand, span, finger, cubit, rod/pole, link, rope, ken, league) are given at their commonly accepted standard sizes — historical local values sometimes differed, so confirm against a primary source before relying on them for legal or historical work.
