About these units
Fingerbreadth (fingerbreadth)
The fingerbreadth, approximately 1.9–2 cm, is the width of an average adult finger and represents one of the smallest practical body-based units. It was historically used for fine measurement in weaving, tailoring, and small-scale construction, complementing units like cubits and handbreadths. Its human-scale precision made it intuitive, particularly in societies without standardized rulers or measuring rods. Fingerbreadths continue to be referenced in scholarly studies of ancient measurements, providing insight into the practical and anthropometric foundations of early 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.
