Metrology plays the key role as the engine of industrial revolution and growth of any country. It promotes global competence and confidence. With the advent of better quality products through metrological advancement, our industries can compete internationally and to overcome trade barriers/constraints and finally to achieve exports targets. This translates into growth of industries through rapid industrialization, economic growth and societal upliftment. The metrology requires continued and sustained efforts to cater the stakeholders’ demands for advancements in measurement technologies, standards and measurement techniques for more and more precise, reliable, reproducible and accurate measurements with improved measurement uncertainties. In this context, the recent revolutionary changes in redefinition of SI units based on fundamental constants were unanimously voted for adoption by world community during November 16, 2018, at Versailles, France, and implemented world over from May 20, 2019—the World Metrology Day. Therefore, it was considered appropriate to compile a brief status report and apprise the readers about these historical events. The present paper touches glimpse of some of these activities and describes the implications of these changes in our daily life.

重新定义的国际单位制及其含义

计量学是任何国家工业革命和增长的引擎，扮演着关键角色。它提高了全球能力和信心。随着计量技术的进步，出现了质量更高的产品，我们的行业可以进行国际竞争，克服贸易壁垒/约束，最终实现出口目标。通过快速的工业化，经济增长和社会进步，这转化为工业的增长。计量需要持续不断的努力，以满足利益相关者对测量技术，标准和测量技术发展的要求，以实现越来越精确，可靠，可再现和准确的测量，并改善测量不确定性。在这种情况下，最近基于基本常数重新定义SI单位的革命性变化于2018年11月16日在法国凡尔赛被国际社会一致投票通过，并于2019年5月20日（世界计量日）在世界范围内实施。因此，认为编写一份简短的状况报告并告知读者这些历史事件是适当的。本文简要介绍了其中一些活动，并描述了这些变化对我们日常生活的影响。
