About nautical league and kilometre
Nautical League: A nautical league is three nautical miles — exactly 5,556 m — a traditional sea-distance unit.
Kilometre: A kilometre is 1,000 metres — the metric unit for road and map distances.
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.
