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.

Chain (US Survey)

The US survey chain is a unit of length used historically in land surveying in the United States. It is defined as exactly 66 US survey feet, which is slightly longer than the international foot. Since one US survey foot equals about 0.3048006096 meters, the US survey chain is approximately 20.11684 meters long.

Like the standard chain, it is divided into 100 links, each measuring 0.66 US survey feet. The US survey chain was widely used in the Public Land Survey System to measure land parcels and boundaries.

Key facts:

1 US survey chain = 66 US survey feet
1 US survey chain ≈ 20.11684 meters
10 US survey chains = 1 furlong
80 US survey chains = 1 US survey mile

Though the US survey foot and chain are being phased out in favor of international units, the US survey chain still appears in historical land records and some legal contexts.
