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.
US Short Ton
Definition: The US short ton is a unit of mass equal to 2,000 pounds (approximately 907.184 kilograms). It is commonly used in the United States for industrial, construction, and freight measurements.
History: The US ton evolved from British weight standards but was adapted to a simpler 2,000-pound definition in the 19th century. This made calculations easier for commerce and industry. Unlike the UK long ton, the US short ton was not influenced by the British imperial system but remained a domestic standard.
Current Use: The US ton is extensively used in the shipping, construction, and manufacturing industries. It appears in cargo shipping, material weight specifications, and fuel measurements, particularly in the United States where metric adoption is limited.
