This date in 1875 was the date the Metre Convention was signed. The Convention created the International Bureau of Weights and Measures and set the framework for global collaboration in the science of measurement and its industrial, commercial and societal applications.

According to estimates by the National Institute of Standards and Technology Office of Weights and Measures, sales of products or services impacted by weights and measures laws in the United States represent approximately 50 percent of the U.S. Gross Domestic Product.

During World Metrology Day more than eighty countries will celebrate the impact of measurement on daily life, no part of which is untouched by this essential and largely hidden aspect of modern society. This year’s theme is “Measurements in Science and Technology: Metrology – a Bridge to Innovation.” Previous themes have included topics such as measurements in sport, the environment, medicine and trade. The 2010 theme concentrates on how measurement influences science and stimulates innovation. Science and technology rely on being able to measure correctly and to refer measurements to the same international reference standards. A world without accurate measurement is a world subject to fraud, error and uncertainty.

National systems of measurement must rely on agreed standards and units as well as agreed techniques to make consistent, reproducible and accurate measurements. Each national system is linked into a world-wide network of national measurement standards and laboratories coordinated by the International Bureau of Weights and Measures. In industry and commerce, this standardization helps ensure product quality, eliminate waste and raise productivity and trade based on agreed measurements and tests. It also enables scientists to use a common language to underpin their collaboration across the world and ensure uniformity wherever companies operate.

NIST will hold its fourth annual celebration of World Metrology Day  on Wednesday, May 20, 2010. The Metre Convention was signed on 20 May 1875, a date now celebrated as World Metrology Day. The Convention created the International Bureau of Weights and Measures (BIPM) and set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal application. The original aim of the Metre Convention – the worldwide uniformity of measurement – remains as important today, in 2010, as it was in 1875. Join us in celebrating World Metrology Day — a celebration of our core foundation and purpose! The theme for 2010 is Measurements in Science and Technology; Metrology – a Bridge to Innovation NIST research and measurements provide a significant foundation for measurements in support of our global economy.  (source www.nist.gov)
