"kg" is an abbreviation for kilogram, but kilograms and kilograms are equivalent, so you can also assume that "kg" is kilograms.
The kilogram (kg) is a unit of mass in the internationally developed International System of Units (SIU), used to measure the mass of an object. It is one of the base units of the International System of Units of Measurement (SI), and is intended to provide a common, standardized unit of measurement for uniformity on a global scale. Its letter abbreviation is "kg".
The origin of the word "kilogram" can be traced back to a French system of measurement first introduced in the 19th century by the French scientist Louis Cayamy de Laplace (Louis Gabriel Cuvier). The kilogram is defined as a mass equal to the mass of a specific platinum-iridium alloy article as defined by the International Atomic Clock Committee. Since then, the definition of the kilogram has been refined and is currently based on Planck's constant, which was redefined in 2019.
Scenarios of use of the kilogram
1. Commercial and retail: the kilogram is commonly used to measure the weight and mass of goods in the shopping and retail industries. Commodities in supermarkets, markets and stores, such as food, vegetables, fruits and meat, are often sold in kilograms.
2, industry and manufacturing: In industrial production and manufacturing processes, kilograms are used to measure the quality of raw materials, components and finished products. Whether manufacturing machinery and equipment, automobiles, electronics or other products, the kilogram is a key unit of measurement.
3. Logistics and Transportation: The logistics and transportation industries often use the kilogram to measure the weight of goods for the purpose of cargo transportation, loading and unloading. The use of the kilogram helps ensure that goods are accurately weighed and safely transported.
4, medical and health: the medical field uses the kilogram to measure the weight of patients, the dosage of medication and the quality of medical equipment. The accuracy of the kilogram is critical to medical treatment and medication administration.
