What is World Metrology Day?

World Metrology Day, also called Weights and Measures Day, is observed every year on May 20 to commemorate the signing of the Metre Convention in 1875, which established a global framework for uniform measurements. This day highlights the importance of metrology;the science of measurement;in fields such as science, industry, trade, and daily life. Accurate measurements are essential for innovation, safety, and international cooperation.

The event promotes awareness of the role measurement plays in technological advancements, economic growth, and sustainability. It is a day for scientific institutions, industries, and governments to recognize the value of precise and reliable measurement systems.

History and Origin

World Metrology Day marks the anniversary of the Metre Convention, which was signed on May 20, 1875, in Paris, France, by representatives from 17 countries. This agreement laid the foundation for the International System of Units (SI) and established the International Bureau of Weights and Measures (BIPM), which ensures global measurement consistency.

Over the years, the importance of metrology has grown with technological progress. Today, World Metrology Day is recognized worldwide, with national and international organizations using it to educate the public about measurement science and its role in everyday life.
