Everything Different, Nothing Changes: Redefinition of the SI Unit Kilogram
17 Jun 2019
In 1889, the 1st General Conference of Weights and Measures (GCPM) adopted the International Prototype Kilogram (IPK) as the definition for the unit, which has remained unchanged until now. In the past, this meant that measuring mass relied entirely on mass accuracy of a physical object, which, even in spite of advanced security measures, has been prone to uncontrollable changes with time. During the last several years , Mettler-Toledo has been privileged to participate in several strategic partnerships that have contributed to the newly established and highly stable kilogram definition. The 1 kg redefinition is part of the biggest overhaul of the International System of Units (SI) since its inception in 1960. This video explains the background of the 1 kg redefinition and the effect this change will have on the weighing world.
