About these units
Span (Cloth) (span)
The span is a unit traditionally used in textile measurement, equal to the distance between the tip of the thumb and the tip of the little finger when the hand is fully extended, approximately 22.86 cm (9 inches). This anthropometric unit was widely used by weavers and cloth merchants to measure lengths of fabric quickly and intuitively. Its small scale made it convenient for practical applications where tape measures or rulers were unavailable. The span also appears in cultural and historical texts as a natural unit of human proportion. While largely obsolete today, it offers insight into pre-industrial textile practices and the anthropometric basis of early measurement systems.
Arpent (arpent)
The arpent is a French unit of length and area, historically used in France and French colonial territories like Louisiana and Canada. As a length, it was roughly 58.47 meters, while as an area unit it varied regionally but was commonly used for agricultural plots. The arpent was central to land measurement, urban planning, and agriculture, particularly in colonies where standard French units were imposed. It helped define plots for farming, taxation, and property distribution, often in combination with other traditional French units such as the perche. Although largely replaced by metric units, the arpent remains significant for historians, geographers, and legal scholars interpreting colonial-era land documents and property records.
