A statute mile is a unit of length commonly used in the United States and the United Kingdom. It is officially defined as 5,280 feet or 1,609.344 meters. The term "statute mile" distinguishes it from other types of miles, such as the nautical mile. The origin of the statute mile dates back to an Act of Parliament in England in 1593, which standardized the length of the mile. It is primarily used for measuring distances on land, such as in road signs, speed limits, and maps. While many countries have adopted the metric system, the statute mile remains in everyday use in a few countries. In contrast to the nautical mile, which is used for air and sea navigation, the statute mile is mainly applied in land-based contexts. It is also used to calculate speed in miles per hour (mph), especially for vehicles and road travel.

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.
