About these units
Barleycorn (barleycorn)
The barleycorn is an English unit, approximately 1/3 inch (8.47 mm), originally based on the length of a grain of barley. It served as a small-scale measure in tailoring, shoe sizing, and other crafts. In particular, the English shoe size system was historically based on barleycorns, with increments in size corresponding to single barleycorn units. This unit exemplifies the anthropometric and agronomic origins of measurement. Even today, the barleycorn's influence persists in the traditional shoe sizing system in the UK and the US, providing continuity with historical practices.
Inch (US Survey) (in (US))
The US Survey Inch is derived from the US survey foot, making it exactly 1/12 of the US survey foot (~2.540006 cm). It is used in precise surveying applications where small differences can accumulate over large distances. Historically, it ensured consistency in cadastral maps, railroad engineering, and construction projects, especially when reconciling legacy measurements with modern geodetic data. Though seldom used outside surveying, the US survey inch highlights the need for consistency and precision in civil engineering and mapping applications.
