World Metrology Day is an annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations, setting 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 SI is now based on a set of definitions each linked to the laws of physics and have the advantage of being able to embrace further improvements in measurement science and technology to meet the needs of future users for many years to come. Indeed more widely metrology, the science of measurement, plays a central role in scientific discovery and innovation, industrial manufacturing and international trade, in improving the quality of life and in protecting the global environment.
