What Is a Kilogram?
One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.
The formal definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.
The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[2] It is equal to the mass of 1,000 cubic centimeters, or milliliters, of water.
The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
