World Metrology Day Poster
“World Metrology Day is an annual celebration of the signature of the Meter Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the framework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Meter Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875.” This information and more can be found at www.worldmetrologyday.org.
