Kilograms
The 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.[1] It is roughly equal to the mass of 1,000 cubic centimeters 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 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
Stones
One stone is equal to 14 pounds and is mostly used in the United Kingdom and Ireland as a unit of mass. It's most commonly used to measure personal body weight.[2]
The stone is an imperial unit of weight. Stones can be abbreviated as st; for example, 1 stone can be written as 1 st.
