Span (Cloth)

A span is an old unit of length based on the distance between the tip of the thumb and the tip of the little finger of a fully extended hand. Traditionally, it measures about 9 inches or 22.86 centimeters.

In the context of cloth and textiles, the span was used as a convenient, informal measure to estimate small lengths of fabric before standardized rulers became widespread. It was helpful for tailors and traders to quickly gauge lengths during measuring and cutting.

While the span is largely obsolete as a formal unit today, it reflects historical measurement practices tied closely to the human body, similar to the cubit or hand.

Summary:

1 span ≈ 9 inches (22.86 cm)
Based on the hand’s spread
Used historically in cloth measurement and tailoring
Now mostly of historical and cultural interest

X-unit

The X-unit (symbol: xu) is a very small unit of length used primarily to measure wavelengths of X-rays and gamma rays. It was introduced in the early 20th century for precision measurements in X-ray crystallography.

1 X-unit ≈ 0.1 picometers (pm) or 10⁻¹³ meters
It allows scientists to express extremely small wavelengths typical of X-rays, which are on the order of atomic spacing
The exact definition has varied historically, but the unit remains useful for comparing wavelengths in X-ray spectroscopy and crystallography

Though largely replaced by the picometer or ångström in modern usage, the X-unit played a crucial role in early developments of atomic-scale measurement.
