2019年世界計量日宣傳海報由中國香港標準和校準實驗室設計(the Standards and Calibration Laboratory, Hong Kong, P.R. China)。

2019年世界計量日的主題是“單位制——本質的提升(The International System of Units - Fundamentally better)”。之所以選擇這一主題，是因為2018年11月16日，計量大會做出了也許是對單位制(SI)自成立以來重要的一次修訂。對包括利用量子現象的種種新式測量方法的研究，奠定了這一重大改變，這些新修訂的內容將于2019年5月20日生效。現在，SI所基于的這組定義都是直接與物理定律一一相關，這一優勢讓我們可以欣然期待測量科學和技術的進一步提升，用戶在未來多年的需求都能因此得以滿足。

事實上，從更廣泛的角度來看，計量學，作為一門測量科學，在科學發現和創新、工業制造和貿易，改善生活質量，以及保護環境等方面都發揮著核心作用。

世界計量日是為了紀念由17個國家的代表于1875年5月20日簽署的《米制公約》而設立的年度慶祝活動。《米制公約》為測量科學及其在工業、商業和社會領域的應用中的合作確定了框架。《米制公約》的制定初衷就是在世界范圍內保證測量的一致性，這一初目標在今天的重要性絲毫不亞于1875年。

World Metrology Day

- 20 May -

The theme for World Metrology Day 2019 is The International System of Units - Fundamentally better. This theme was chosen because on 16 November 2018, the General Conference on Weights and Measures agreed perhaps one of the most significant revisions to the International System of Units (the SI) since its inception. Research into new measurement methods, including those using quantum phenomena, underpin the change, which comes into force on 20 May 2019. The SI is now based on a set of definitions each linked to the laws of physics and have the advantage of being able to embrace further improvements in measurement science and technology to meet the needs of future users for many years to come.

Indeed more widely metrology, the science of measurement, plays a central role in scientific discovery and innovation, industrial manufacturing and international trade, in improving the quality of life and in protecting the global environment.

World Metrology Day is an annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the fr amework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875.

The World Metrology Day project is realized jointly by the BIPM and the OIML. We hope that you enjoy this site and that your Country or   Metrology Organization will join us and participate in this year's event.

Warm regards,
