The platinum and iridium alloy cylinder (pictured on November 16, 2018 at the Czech Metrology Institute in Brno, Czech Republic) will no longer be a kilogram standard. Representatives of individual countries at the International Bureau of Weights and Measures (BIPM) conference, as expected, have decided to redefine the kilogram and other basic units. The base unit of mass is newly derived from the fixed value of the Planck constant. (CTKxPhoto IgorxZehl) CTKPhotoP201811160672001
