Quantum SI: The New System of Units

Abstract

This article gives an overview of the new SI and a few details as to how its setting up was achieved. Those interested in the story of how the kilogram was fixed by tying it to the Planck constant can go straight to section five. Otherwise, apart from the introduction given as section one which also presents excerpts from the relevant official documents on key aspects of the new system, section two gives a brief timeline of the history of the decimal metric system, section three gives a few details of the procedural steps -- from the setting up of a standard of measurement to its percolation to the public, taking the time standard as an example and, section four attempts to give a flavour of the actual process of the setting up of a standard.
