World Metrology Day – 20 May 2019

May 20 is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in 1875. This treaty provides the basis for a coherent measurement system worldwide 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 2019 is The International System of Units - Fundamentally better. This theme was chosen because on 16 November 2018, the General Conference on Weights and Measures agreed perhaps one of the most significant revisions to the International System of Units (the SI) since its inception. The 20th May this year is a particularly special edition of World Metrology Day because it is the day chosen for the implementation of the changes agreed to the definitions of the SI units.

World Metrology Day recognizes and celebrates the contribution of all the people that work in intergovernmental and national metrology organizations throughout the year on behalf of all.

Every year, the National Institute of Metrology is celebrating the World Metrology Day by opening its doors to all interested parties and informing the public on the developments and news in the field.
