Units explained
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.
Barleycorn
A barleycorn is an Imperial unit of length equal to one third of an inch (about 8.47 mm). It is the basis of UK shoe sizing and is one of the oldest English length units still in use.
The barleycorn derives from the average length of a grain of barley as a natural reference. Standardised at exactly 1/3 inch by the Statute of Edward II in 1324, which used three barleycorns to define an inch.
Barleycorns are the foundation of UK and US children's shoe sizing — each whole size differs by one barleycorn. Also occasionally referenced in horse-handling and historical English literature.
Standardised in 1324 by the Statute of Edward II at 1/3 inch; the value became exact in 1959 when the inch was fixed at 25.4 mm.
