這些國際計量體系為測量的準確性提供了必要的保證和信心，為當今的全球貿易奠定了堅實基礎，并幫助我們為應對未來挑戰做好準備。

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.

世界計量日旨在肯定和頌揚所有工作在政府間組織、區域組織和國家計量機構中的人們一年來為計量所做的貢獻。2023年11月，聯合國教科文組織（UNESCO）第42屆大會正式承認每年5月20日的世界計量日慶祝活動，這是一個重要里程碑。這一認可凸顯了計量在推動全球科學合作中發揮的關鍵作用，為促進計量發展開辟了新的途徑，并與聯合國教科文組織“通過科學和教育建設更美好世界”的使命相吻合。

World Metrology Day acknowledges and honors the contributions of individuals working in intergovernmental, regional, and national metrology organizations and institutes year-round. In November 2023, a significant milestone was reached as the UNESCO General Conference, during its 42nd Session, officially recognized the celebration on 20 May annually. Underscoring its pivotal role in advancing global scientific cooperation, this endorsement opens up new avenues to promote metrology, aligning with UNESCO's mission to build a better world through science and education.
