Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined as the mass of the International Prototype Kilogram, a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures.
History/Origin
The kilogram was originally defined in 1795 as the mass of one liter of water. It was later represented by a platinum standard in 1875, known as the International Prototype Kilogram, which served as the global standard until 2019.
Current Use
Today, the kilogram is defined by the Planck constant, fixed at exactly 6.62607015×10⁻³⁴ joule seconds, ensuring greater precision and stability in measurements worldwide. It is widely used in science, industry, and commerce for measuring mass.
Quarter (Uk)
A quarter (qr) is a traditional unit of weight used in the UK, typically equal to one-quarter of a hundredweight, or 28 pounds (approximately 12.7 kilograms).
History/Origin
The quarter has historical roots in British measurement systems, originating from the need to divide larger weights into manageable parts. It was commonly used in trade and agriculture before the adoption of the metric system.
Current Use
Today, the quarter is largely obsolete in official measurement but may still be used informally in certain industries such as agriculture and livestock to denote weight, especially in the UK.
