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.
Microinch (µin)
A microinch is one-millionth of an inch, approximately 2.54 × 10⁻⁸ meters. It is a precision unit used primarily in engineering, machining, and electronics. Microinches allow engineers to describe tolerances, surface roughness, and component dimensions with extreme accuracy. This is especially relevant in semiconductor manufacturing and microelectronics, where deviations of just a few microinches can impact performance. Although rarely encountered outside technical fields, the microinch demonstrates the need for highly granular units in modern technology, bridging the gap between traditional inches and nanometer-scale measurements.
