CSIR-NPL introduce Redefined International System of Units

Council of Scientific and Industrial Research and National Physical Laboratory, CSIR-NPL, today introduced redefined International System of Units for the country, on World Meterology Day. 

The redefined systems are kilogram, kelvin, mole and ampere. The purpose of a system of units is to enable world-wide coherence of measurements. 

Speaking on the occasion in New Delhi, former Scientific Advisor to Defence Ministry Dr R Chidambram said this is  a revolutionary change. He said the country should increase its  calibration and measurement capabilities.
 CSIR-NPL has also prepared documents on NPL policy on Meterology Traceability and recommendations on proposed changes to be incorporated in the National Council of education Research and Training textbooks. 

AIR correspondent reports the International system of Units-SI was formalised in 1960, and has been d several times to account for advances in measurement technology.

Since the 1960s,  the country has  come to rely ever more heavily on advanced science and engineering in day-to-day lives, and also in manufacturing, health-care and science. The proposed changes in the unit definitions have been designed to have no immediate consequence.
