As part of World Metrology Day, Directorate for Measures and Precious Metals (hereinafter: DMDM) ​​hosted the students from the Faculty of Civil Engineering at the University of Belgrade, on Friday, May 17, 2024.

Students were introduced with the importance of metrology, as a science of measurements. Measurements are  present in all areas of human activity. The main role of metrology is to ensure the metrological traceability to the international level and to point out the long tradition of metrology in Serbia.

Also, students were informed about the theme of the World Metrology Day 2024 "We measure today for a sustainable tomorrow", which is given special attention because measurement capabilities are key to fostering a sustainable global economy and environment.

Through the promotional film, the importance and role of DMDM, as a national metrology institution, its competences, jobs and tasks in the field of metrology were presented.

The expert visit included a tour of the laboratories for time, large volumes, acoustics, length and mass.

During the visit to the laboratories, the students had the opportunity to become more familiar with the possibilities of measurement and calibration, as well as other tasks that DMDM ​​performs as a national metrology institute.

Directorate for Measurements and Precious Metals (hereinafter: DMDM) celebrated World Metrology Day. Celebration took place in the most beautiful oasis of the city of Belgrade, the Botanical Garden "Jevremovac", on Monday, 20^th of May 2024.

World Metrology Day is celebrated on the occasion of the anniversary of the signing of the Meter Convention, which in 1875 established a framework for international cooperation in the field of metrology for industrial, commercial and social applications. As a signatory to the Meter Convention since 1879, Serbia has been applying the International System of Units for 145 years.

Every year, more attention is paid to a certain topic, so this year, we celebrate the World Metrology Day on the topic "We measure today for a sustainable tomorrow". Sustainability, as the theme of World Metrology Day 2024, was chosen because measurement capabilities are key to fostering a sustainable global economy and environment.

Cedomir Belic, director of DMDM, opened the meeting by greeting the attendees and pointed out that this year is particularly significant. During the 42nd session of the UNESCO General Conference, the annual observance of May 20th as World Metrology Day was officially recognized. This recognition opens up new approaches for the promotion of metrology, aligning with UNESCO's mission to build a better world through science and education.

The panel discussion on the topic "We measure today for a sustainable tomorrow" was introduced by the moderator Marina Radojevic, employed at DMDM ​​as quality management representative. The panelists were PhD Vladimir Djurdjevic - Faculty of Physics, PhD Ana Vukovic Vimic - Faculty of Agriculture, PhD Tomica Misljenovic - Faculty of Biology and PhD Dusan Matijasevic, metrologist in the Group for Electrical Measurements in DMDM.

Participants in the panel discussion emphasized on the importance of metrology in  21st century, considering all the challenges that await us due to climate changes. Some of this challenges include global warming, the occurrence of extreme weather events, as well as the impact of air pollution on the living world. Focus is on development and application of clean energy sources in future.

After the panel discussion, a cocktail party was organised for all guests in the pleasant surroundings of the Botanical Garden with musical performances of the string quartet in the background.  A group tour of the Botanical Garden with an expert guides were arranged as well.
