About these units
Vara Conuquera (vara conuquera)
The Vara Conuquera is another regional variant of the vara, used primarily in Chile, with a slightly different length than the standard vara. It was closely associated with land measurement, particularly in defining plots for cultivation and property boundaries in rural communities. Its use highlights the way local measurement systems adapted colonial Spanish units to meet practical needs. Land surveyors, farmers, and municipal officials relied on the Vara Conuquera for legal documentation, taxation, and irrigation planning. Today, knowledge of the Vara Conuquera is mostly of historical and legal interest, providing context for land disputes, heritage records, and the evolution of measurement in Chilean history.
X-unit (X)
The X-unit is an extremely small length, approximately 1.002 × 10⁻¹³ meters, historically used to express X-ray and gamma-ray wavelengths. The unit was invented before modern standards for measuring electromagnetic wavelengths existed, allowing scientists to describe extremely short wavelengths without resorting to scientific notation. X-units were valuable in crystallography and atomic physics in the early 20th century, enabling precise description of spectral lines emitted by X-ray sources. Although modern practice has largely replaced the X-unit with the nanometer or picometer, it continues to appear in historical literature. The unit's existence highlights how scientific progress shapes measuring conventions. Once essential, the X-unit now serves as a bridge to the history of early atomic research.
