World Metrology Day 2015
11 May 2015
World Metrology day provides an opportunity to promote the importance of metrology. Metrology is the science of measurement and its application. Metrology includes all theoretical and practical aspects of measurement, whatever the measurement uncertainty and field of application.
This year, World Metrology Day is aligned with the International Year of Light and Light-based Technologies proclaimed by the General Assembly of the UN and organized by UNESCO. Events in 2015 will celebrate the central role of light to life, whether as a source of energy, as the basis for photonic technologies or as being a source of wonder and excitement. Metrology plays a central role in enabling the application and advancement of light-based technologies, whether for more efficient energy production, a better understanding of climate change, or optimal lighting of our cities and towns. In turn, light is at the heart of many of the most important new elements of leading-edge measurement technologies.
Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at whatever level of sophistication is needed. They also participate in comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) to ensure the reliability of measurement results worldwide.
World Metrology Day recognises and celebrates the contribution of all the people that work in intergovernmental and national organisations throughout the year on behalf of all.
