Chilogrammo - Wikipedia. Il chilogrammo (grafia alternativa: kilogrammo) [1] [2], nell'uso parlato comunemente chilo [3] [4] (simbolo: kg [5] ), è l' unità di misura di base della massa nel Sistema internazionale di unità di misura (SI) [6] corrispondente alla massa di ≈ 4,595 × 107 mP, (relazione con la massa unitaria di Planck).
The kilogram is the base unit of mass in the International System of Units (SI). It is widely used in science, engineering, and commerce worldwide. The kilogram is exactly the mass of one litre of water. As of May 20, 2019, the definition of the kilogram is based on the Planck constant as 6.626 070 15 × 10 −34 kg⋅m 2 ⋅s −1.
The International Prototype of the Kilogram (referred to by metrologists as the IPK or Le Grand K; sometimes called the ur-kilogram, or urkilogram, particularly by German-language authors writing in English:30: 64 ) is an object whose mass was used to define the kilogram from 1889, when it replaced the Kilogramme des Archives, until 2019, when ...
2019 definition: The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10−34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and ΔνCs.
The kilogram is the base unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'.
25 apr 2024 · Kilogram, basic unit of mass in the metric system. A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. It was once defined in terms of a platinum-iridium cylinder, but in 2018 the CGPM agreed to define it in terms of Planck’s constant.
