India New Scientific Tender

The prototype of one kilogram NPK-57 is already available in India and placed at National Physical Laboratory New Delhi as per the provisions made under the Legal Metrology National Standards Rules 2011.There is no such proposal at present before the Government to achieve the new prototype of kilogram through physical constants.The previous definition of kilogram was based on the mass of the international prototype kilogram which is an artefact however the new definition is based on physical constants of nature. The change is in the definition of kilogram and will not have any practical implications.
