New definitions of scientific units in 2018

On Friday, 20 October, the 106th meeting of the International Committee for Weights and Measures (CIPM) submitted a resolution recommending the redefinition of four base units (the kilogram, the ampere, the kelvin and the mole) of the International System of Units (SI) based on exact values of four fundamental constants. These recommendations will then go before the General Conference on Weights and Measures (CGPM), which oversees the SI, for final worldwide agreement in November 2018. The changes would take effect on 20 May 2019, World Metrology Day.

“The decision by the CIPM to propose a resolution to the 26th CGPM on the redefinition of base units in the SI brings the vision of an International System of Units based on invariant constants of nature one step closer to realization. In taking this decision, the CIPM acknowledges the outstanding contributions by many metrologists and the commitments of their institutes to undertake the long-term experiments necessary to make this decision possible.” Dr Barry Inglis, President of the CIPM

„The Directorate of Measures and Precious Metals – DMDM as representative of the Republic of Serbia in all this international bodies, recognized extraordinary importance of decision to redefine the base SI units and thereby establish connection of all measurements with invariant natural constants“

Mr. Čedomir Belić, Acting Director of DMDM
