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.
Ell
An ell is an Imperial unit of length equal to 45 inches (1.143 m), historically used as the standard measure of cloth in English commerce.
The ell derives from old English elna (forearm) and was standardised in medieval English trade as the cloth-measuring yard equivalent. The English ell is 45 inches; other regional ells differed.
Ells appear in historical English commerce records (especially cloth and tapestry trade). Used in legal documents through the 19th century; rare in modern commerce but referenced in literary and historical contexts.
Medieval English cloth-trade origin; standardised at 45 inches; became exact via the 1959 International Yard and Pound Agreement.
