World Metrology Day

World Metrology Day

World Metrology Day is an annual event during which the impact of measurement on our daily lives is celebrated around the world.

This date was chosen in recognition of the signing of the Metre Convention on 20 May 1875, the beginning of formal international collaboration in metrology. Each year World Metrology Day is organised and celebrated jointly by the International Bureau of Weights and Measures (BIPM) and the International Organization of Legal Metrology (OIML) with the participation of the national organisations responsible for metrology.

The international metrology community which works to ensure that accurate measurements can be made across the world endeavours to raise awareness each World Metrology Day through a poster campaign and web site. Previous themes have included topics such as measurements for the global energy challenge, for safety, for innovation, and measurements in sport, the environment, medicine and trade.
