Kilogram (kg)
Definition: The kilogram (kg) is the SI base unit of mass, defined in terms of the Planck constant. It is the standard for measuring weight and mass globally in science, industry, and daily life, ensuring consistency and precision in various applications.
History: The kilogram was originally defined in 1795 as the mass of one liter of water at 4°C. In 1889, a platinum-iridium cylinder was designated as the International Prototype Kilogram. Due to minor fluctuations in its mass, the definition was revised in 2019 to be based on the Planck constant (6.62607015 × 10⁻³⁴ m²kg/s), making it independent of any physical object and ensuring long-term precision.
Current Use: The kilogram is widely used in global trade, industry, and scientific research. It serves as the foundation for measuring mass across multiple fields, from food and medicine to physics and engineering, ensuring standardization in both commercial and scientific settings.
UK Long Ton
Definition: The UK long ton, also called the imperial ton, equals 2,240 pounds or approximately 1,016 kilograms. It was widely used in British commerce and shipping before the UK adopted the metric system.
History: The long ton dates back to medieval England, where various ton weights were used for measuring bulk goods. It was standardized in the 19th century under the British Weights and Measures Act. Although largely replaced by metric units in the UK, it remained influential in naval and international trade for centuries.
Current Use: The UK long ton is mostly obsolete but still appears in maritime freight and historical records. It is occasionally used in industries where British imperial measurements were historically significant, such as shipbuilding and military logistics.
