World Metrology Day – 20 May 2023
Measurements supporting the global food system
Welcome to the 2023 World Metrology Day Resource website. The theme for World Metrology Day 2023 is Measurements supporting the global food system.
This theme was chosen because of the increasing challenges of climate change, and global distribution of food in a world whose population reached 8 billion at the end of 2022.
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 framework 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.
