Happy new year 2019... On 16 November 2018, the 60 Member States of the Metre Convention unanimously voted to recast the International System of Units.
This vote is a historic event because, for the first time since the signing of the Metre Convention in 1875, four units: the kilogram, the mole, the ampere and the kelvin, have been redefined on the basis of fundamental natural constants. It also marks the end of the use of material artifacts for unit definition.
These redefinitions have been made possible thanks to the research efforts of the international metrological community, and in particular, by the research work carried out for many years by LNE and the laboratories of the French National Metrology Network on the redefinition of the kilogram, the ampere and the kelvin.
In 2019, LNE will continue its involvement by conducting training and support activities for the scientific community and industrialists. The industry must be able to rely on measurements traceable to internationally recognised references, as reliable as possible, in often extreme conditions or environments: towards the world of nanos, very high temperatures, positioning or long distances. The evolution of the IS will open up new fields of expertise in health, biology, climate change monitoring or the development of quantum technologies...
These new definitions will thus make it easier to meet the needs of the industry with ever finer accuracy, and certainly to see the emergence of new innovations.
With this mission in mind, we are supporting manufacturers and society towards this new era that is emerging in 2019.
