Metrology Symposium 2019

(11 January 2019)

The Council, Government Laboratory, the Open University of Hong Kong and the Standards and Calibration Laboratory (SCL) of Innovation and Technology Commission co-organised the Metrology Symposium 2019. (Programme)

The International System of Units made a major revision of the SI, the foundation of measurements on May 20, 2019. Four of the seven SI base units namely kilogram, ampere, kelvin and mole were redefined based on the fundamental constants, which removed the current limitations imposed by the use of artefact standards. The change would bring significant impacts and further developments to the modern world.

The poster designed by SCL was selected as the poster of the World Metrology Day 2019. The design ideas were based on modern world is becoming smarter with many smart technologies such as artificial intelligence (AI), big data, robotics, virtual reality (VR), 5G and autonomous vehicles etc., in which they are all built on smart sensors and transducers and rely on precision measurements. With better foundation of metrology, a better and smarter world can be built. This Symposium attempted to unfold to the local testing and certification industry as well as the parties interested in metrology how the revision of SI would enable us to embrace further improvements in measurement science and technology for a better and smarter world.
