Welcome New Era of Measurement on World Metrology Day!

News Bharati    20-May-2019

New Delhi, May 20: Today is the World Metrology Day. On this occasion the entire world has adopted a historic scientific change, particularly in the field of measurement. New units of kilogram, kelvin, mole and ampere will be in application from today onwards!

On 16th November 2018, in an open session of the General Conference on Weights and Measures (CGPM) at BIPM, the world’s scientific and technical community unanimously adopted the resolution to redefine four of the seven base units, the kilogram (SI unit of weight), Kelvin (SI of temperature), mole (SI unit of amount of substance) and ampere (SI unit of current).


The decision has now enabled the scientists to base the SI units entirely on fundamental properties of nature, thereby ensuring their ongoing refinement and improvement for years to come.

The World Metrology Day (WMD) is celebrated annually on 20th of May as the Metre Convention was signed by representatives of seventeen nations on May 20, 1875. The convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications.

"Quantum Coumputing, Artificial Intelligence (AI), Inddustry 4.0, Space Enabled Communications are some of the international challanges of the near future and it is necessary for India, the fastest growing economy to make the triumps to meet the above challanges with the support of quantum metrology based quantity infrastructure," said DG CSIR Shkehar C. Mande congratulating the NPL in bringing out the new units.

The CSIR-NPL on this historic day introduced redefined SI units to nation in terms of constant of nature through a series of events like lectures, releasing posters, preparation of documents, etc. the theme for this year’s WMD is “The International System of units – Fundamentally Better”.

The CSIR-NPL has also published a book entitled “Redefined SI units and Glimpses of NPL Metrological Activities” of nearly 100 pages to percolate and disseminate the information comprising of details on new changes, posters and documents mentioned above and the role of NPL in strengthening the Indian Metrological infrastructure for the government representatives, policy makers, regulator, certification bodies, academic institutions, industries and public as a whole.
