2019 edition of World Metrology Day (WMD)
The World Metrology Day (WMD) is observed every year on May 20 to commemorate anniversary of the signing of the Metre Convention in 1875. The 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 2019 theme is “The International System of Units – Fundamentally better”. The International System of Units is now based on a set of definitions each linked to the laws of physics and has 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.
