New SI System of Measurement Comes into Effect in India
The new SI system of measurements have come into effect redefining four of the seven base units, the kilogram (SI unit of Weight), Kelvin (SI unit of temperature), mole (SI unit of substance) and ampere (SI unit of current).
The redefined units were adopted at the General Conference on Weights and Measures (CGPM) at BIPM in November and has come into effect on World Metrology Day, May 20.
DG CSIR, Shri Shkehar C. Mande informed that CSIR-NPL introduced redefined SI Units in India in terms of constant of nature through a series of events, delivering lectures, releasing theme (The International System of Units – Fundamentally Better) based poster of BIPM; release of NPL’s designed posters introducing redefined SI to nation highlighting fundamental constant of nature and impact of metrology on all walks of human life; release of poster on technologies transferred, commercialized, patents filed / granted, number of customer served through testing and calibrations by CSIR-NPL during 2018-2019, release of poser on Bhartiya Nirdeshak Dravya (BND) and release of new NPL certified BNDs.
As a national responsibility and keeping in view of the importance and recognition of new revision of SI, the CSIR-NPL has also prepared documents on i) NPL Policy on Metrological Traceability, ii) recommendations on the proposed changes to be incorporated in the National Council of Educational Research and Training (NCERT), New Delhi textbooks and implement the new changes to impart cotemporary education to its students and iii) recommendations on the proposed changes to be incorporated in syllabi of metrology courses in graduate engineering and academic courses being taught in All India Council for Technical Education (AICTE), Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), and other academic institutes.
On this occasion CSIR-NPL also published a book entitled, “Redefined SI Units and Glimpses of NPL Metrological Activities” of almost 100 pages to percolate and disseminate the information accommodating details on new changes, posters and documents mentioned above and role of NPL in strengthening the Indian metrological infrastructure for the govt. representatives, policy makers, regulator, certification bodies, academic institutions, industries and public as a whole.
