May 20 is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in 1875. This treaty provides the basis for a worldwide coherent measurement system that underpins scientific discovery and innovation, industrial manufacturing and international trade, as well as the improvement of the quality of life and the protection of the global environment.
5月20日是世界計量日，以紀念1875年《米制公約》簽署日。該公約為全球一致的測量系統奠定了基礎，該系統是科學發現和創新、工業制造和國際貿易以及提高生活質量和保護全球環境的基礎。

The theme for World Metrology Day 2020 is Measurements for global trade. This theme was chosen to create awareness of the important role measurement plays in facilitating fair global trade, ensuring products meet standards and regulations, and satisfying customer quality expectations.
2020年世界計量日的主題是“全球貿易計量” 。選擇該主題的目的是提高人們對計量在促進公平全球貿易，確保產品符合標準和法規以及滿足客戶質量期望方面的重要作用的認識。

Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at the necessary level of sophistication. The national metrology institutes participate in measurement comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) to ensure the reliability of measurement results worldwide.
在世界范圍內，國家計量機構通過在必要的復雜程度上開發和驗證新的計量技術，不斷推進測量科學的發展。國家計量機構參與國際計量局（BIPM）協調的國際比對，以確保全球測量結果的可靠性。

The International Organization of Legal Metrology (OIML) develops International Recommendations, which aim to align and harmonise requirements worldwide in many fields. The OIML also operates the OIML Certification System (OIML-CS) which facilitates international acceptance and global trade of regulated measuring instruments.
國際法定計量組織（OIML）制定了國際建議，旨在協調和統一世界范圍內許多領域的要求。OIML還運行OIML認證系統（OIML-CS），該系統促進受管制測量儀器的國際接受和全球貿易。

These international metrology systems provide the necessary assurance and confidence that measurements are accurate, providing a sound basis for global trade today and helping us to prepare for the challenges of tomorrow.
這些國際計量系統為計量準確提供了必要的保證和信心，為今天的全球貿易提供了良好的基礎，并幫助我們為明天的挑戰做好準備。

World Metrology Day recognises and celebrates the contribution of all the people that work in intergovernmental and national metrology organisations and institutes throughout the year.
世界計量日表彰和慶祝所有在政府間和國家計量組織和研究所工作的人全年所作的貢獻。
