(BIPM: Saint-Cloud, France) -- May 20, 2023, 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.

The theme for World Metrology Day 2023 is “Measurements supporting the global food system.” This theme highlights the increasing challenges of climate change and global distribution of food in a world whose population reached eight billion at the end of 2022.

Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at the necessary level of sophistication. 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.
