Units explained
Finger
A finger is an Imperial unit of length equal to 4.5 inches (114.3 mm). It is one of the historical English cloth-measure units.
The finger derives from English cloth-trade tradition, where it was used as a small measure for ribbons and small fabric pieces. Standardised at 4.5 inches through English customary practice.
Fingers are rare in modern use; they appear primarily in historical English textile records and bartending (where 'a finger of whisky' is an informal usage roughly 1 inch, not 4.5).
Medieval English cloth-trade origin; standardised at 4.5 inches; the value became exact via the 1959 International Yard and Pound Agreement.
Perch
A perch is an Imperial unit of length identical to the rod — 16.5 feet (about 5.03 m). The names 'rod', 'perch', and 'pole' all refer to the same surveying unit and differ only by regional preference.
Like the rod, the perch derives from medieval English land-surveying. The name 'perch' was particularly common in legal land descriptions in Ireland and parts of the UK.
Perches appear in legacy land descriptions in Ireland, the UK, and historical US documents. Modern usage is rare.
Medieval English surveying origin; identical to the rod since 1620; became exact via the 1959 International Yard and Pound Agreement.
