About the webinar
The 2026 theme highlights the role of metrology in providing reliable and comparable data to support policy decisions and public trust.
The webinar will examine how measurement and regulatory frameworks interact with emerging technologies, including artificial intelligence, and how these relationships can support innovation while maintaining transparency and confidence in data.
For examples of how reliable measurements empower better policy, accelerate innovation and create the foundation for global trust and collaboration, watch our video "How Can Metrology Support Global Policy?"
Background
World Metrology Day is celebrated annually on 20 May to commemorate the signing of the Metre Convention in 1875, which established international cooperation in measurement science and created the framework for the BIPM.
UNESCO first celebrated World Metrology Day in 2024 following a decision of its 42nd General Conference in 2023. This reflects the growing recognition of the importance of accurate, internationally recognized measurements in addressing global challenges, including sustainable development, public health and technological innovation.
The BIPM works with Member States, National Metrology Institutes and international partners to ensure the global comparability of measurements and to support the International System of Units (SI).
This year’s joint webinar contributes to the International Decade of Sciences for Sustainable Development (2024–2033).
