Measurements and Light
On 20 May 2015, World Metrology Day will join the 2015 International Year Light (iyl2015.org), with day-long celebrations on the theme of Measurements and Light.
World Metrology Day celebrates the signature by representatives of seventeen nations of the Metre Convention on 20 May 1875. The Convention 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 as it was in 1875.
The World Metrology Day project is realized jointly by the Bureau International des poids et Mesures (BIPM) and the International Organization of Legal Metrology (OIML). We hope that you enjoy this site and that your Country or Metrology Organization will join us and participate in this year’s event.
