Units explained
League
A league is an Imperial unit of length equal to 3 miles (about 4.83 km). It is one of the oldest distance units in English usage, historically representing the distance a person could walk in one hour.
The English league derives from the ancient Roman leuga via medieval English customary practice. Standardised at 3 statute miles in English law.
Leagues appear in historical English literature ('seven-league boots'), maritime navigation (a nautical league is 3 nautical miles), and traditional distance descriptions. Modern usage is largely literary.
Medieval English customary origin; standardised at 3 miles; became exact via the 1959 International Yard and Pound Agreement.
Nail
A nail is an Imperial unit of length equal to 2.25 inches (about 57.15 mm). It was historically used in the English cloth trade.
The nail derives from an English cloth-measure tradition dating to medieval times. Standardised at 2.25 inches (or 1/16 of a yard) through English customary practice and ratified by the 1959 International Yard and Pound Agreement.
Nails were historically used to measure cloth, particularly small pieces and ribbons. Rare in modern commerce but appears in historical textile literature and reproduction crafts.
Medieval English cloth-trade origin; standardised at 1/16 yard; fixed exactly at 0.05715 m via the 1959 International Yard and Pound Agreement.
