  • The new artefacts must be derived from the constants of nature that are all interdependent.
  • These include constants such as the Planck constant.
  • Planck constant is the ratio of the electromagnetic radiation from a photon to its frequency and the charge of an electron.
  • Presently a salt-shaker-sized cylinder housed at the Bureau International des Poids et Mesures (BIPM), Paris and weighing exactly a kilogram served as the definition of the measure. 
  • National Physical Laboratory of India too has a replica of this, since 1957, and it has served as the reference for a variety of industries to keep their weights accurate.
