About these units
Cubit (UK) (cubit (uk))
The UK cubit is a traditional English unit derived from the length of the forearm, roughly 0.4572 meters (18 inches). It was historically used in construction, land measurement, and woodworking, providing a human-scale reference for practical tasks before standardized units were widely adopted. In England, the cubit also played a role in surveying and architectural planning, often subdivided into smaller units such as hands or fingers for precision. Builders and craftsmen relied on the cubit because it allowed approximate measurement without instruments, a feature especially valuable in early medieval and pre-industrial periods. Although replaced by the foot and yard over time, the cubit remains an important historical reference for studying British architecture, surveying records, and early measurement systems.
Foot (US Survey) (ft (US))
The US Survey Foot is a standardized version of the foot, defined as exactly 1200/3937 meters (~0.30480061 m). It was adopted to maintain continuity with older surveying records when converting to the metric system. Surveyors, engineers, and geographers in the United States used this unit for mapping, cadastral surveys, and infrastructure projects. Its slight difference from the international foot allows historical survey data to align accurately with modern geodetic coordinates. Although the international foot is now more common, the US survey foot remains relevant for interpreting historical survey data and legal property boundaries.
