Units explained
Rope
A rope is an Imperial unit of length equal to 20 feet (6.096 m). It was historically used in English customary measurement, particularly in masonry and some land contexts.
The rope derives from English customary practice and represents 20 feet. Less commonly used than the rod-perch-pole family.
Ropes appear in historical English construction and surveying records but are rare in modern practice. Some legacy specifications and contracts may still reference the unit.
Medieval English customary origin; standardised at 20 feet; 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.
