Metrology can be defined as the science of measurement and its application.
World Metrology Day commemorates the contribution of all those who work in intergovernmental and national metrology organizations and institutes, across the globe.
World Metrology Day is an annual celebration of the signature of the Metre Convention on May 20, 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 theme for World Metrology Day 2022 is Metrology in the Digital Era. This theme was chosen because digital technology is revolutionizing our community, and is one of the most trending topics in society today.
