Will one kilogram always be equal to one kilogram? To find out more, read the conclusions, concerning the kilogram and more broadly the revision of the International System of Units (SI), of the 26th meeting of the General Conference of Weights and Measures (GFCM) which met recently.

This mass unit (symbol kg) will, from May 20, 2019, be defined from the Planck constant and no longer from a physical object.

Indeed, since 1889, the kilogram is equal to the mass of a platinum iridium cylinder (the famous prototype also called the “big K”) which is kept in Sèvres in the premises of the International Bureau of Weights and Measures (BIPM) .

This is particularly to have a uniform and accessible IS worldwide in many sectors of activity (international trade, high technology industry, human health …) but also to have stable measurement units in the long run the kilogram has been redefined.

To note :

As part of this 26th CGPM, the definitions of ampere, kelvin and mole have also been revised.
