Units explained
Pole
A pole is an Imperial unit of length identical to the rod and perch — 16.5 feet (about 5.03 m). The names are regional and historical variants for the same measurement.
The pole derives from medieval English land-surveying. The name comes from the physical wooden pole used by surveyors to lay out the unit on the ground.
Poles appear in historical land records, particularly older US public-land surveys. Functionally identical to rod and perch in all calculations.
Medieval English surveying origin; identical to the rod since 1620; 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.
