(The Gist of Science Reporter) Kilogram Redefined [JANUARY-2020]
(The Gist of Science Reporter)
Based on a historic decision at the General Conference on Weights and
Measures in Versailles, France, organised by the International Bureau of
Weights and Measures (BIPM), all the SI units would now be defined in terms
of constants that describe the natural world. Four fundamental units —
Kilogram , Kelvin , Mole & Ampere — have undergone a change which came into
force worldwide on the World Metrology Day celebrated on 20 May 2019.
