Convert Hundredweight (UK) to Kilogram
Hundredweight (UK)
The hundredweight (UK) is a unit of mass used in the United Kingdom, primarily in agriculture and industry. It is equal to 112 pounds or approximately 50.8 kilograms. The hundredweight is part of the British Imperial system and is used to measure bulk commodities like grain and livestock.
The hundredweight originated in medieval England as a unit of mass for measuring grain and other agricultural products. It was defined as 112 pounds. The term "hundredweight" comes from the Latin word "centum", meaning "hundred". The hundredweight was used in trade and agriculture for centuries and continues to be used in the UK as part of the British Imperial system.
Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined based on the Planck constant (h), a fundamental constant of nature.
1 kilogram is the mass that corresponds to the fixed numerical value of the Planck constant (h), which is 6.62607015 × 10⁻³⁴ joule-seconds (J·s), when expressed in the SI unit J·s = kg·m²·s⁻¹.
This modern definition ties the kilogram to a constant of nature rather than a physical object, ensuring its precision and stability over time.
Before this redefinition, the kilogram was defined as the mass of the International Prototype of the Kilogram (IPK), a physical platinum-iridium cylinder stored in France.
The kilogram originated during the French Revolution in the late 18th century as part of the metric system's development. Initially, it was defined as the mass of one cubic decimeter of pure water at 4°C, chosen for its universal availability and consistency. In 1799, a physical standard called the Kilogram of the Archives, a platinum cylinder, was created to represent the unit. Later, in 1889, the International Prototype of the Kilogram (IPK), a more precise platinum-iridium cylinder, was adopted as the global standard, stored in France with copies distributed worldwide.
Over time, physical changes in the IPK led to inconsistencies, prompting scientists to redefine the kilogram. In 2019, it was redefined based on the Planck constant (h), a fundamental constant of nature, linking the kilogram to unchanging physical properties rather than a physical object. This modern definition ensures long-term precision and stability for the unit of mass.
